The philosophy for YS Master Pieces is simple: everything produced must be of such high quality and detail that I would want to purchase the item, myself. Initially the models produced will represent the warships of the late 19th and early 20th century. I love the shape of the ships of that era because of their complex appearance and their many curves. 

Only the finest materials are used and I strive to insure that every component and part that goes into a YS Master Pieces model warship is of the highest level of craftsmanship possible. All components are produced here in Hellas (Greece), except for the Photo-Etch etching process and boxes, which are from the United Kingdom.

USS Oregon, BB-3
YS Master Pieces Kit in 1:350 Scale

YS Master Pieces newest 1:350 resin kit is the USS Oregon. This one piece full hull model portrays the ship as she appeared during the Spanish-American War of 1898. The third of the three ship Indiana Class, Oregon and her sisters Indiana, BB-1 and Massachusetts, BB-2 were the first modern USN battleships designed to equal the fighting power of contemporary European designs. Their armament of four 13 inch and eight 8 inch guns were as powerful as any European design and her armor belt of 18 inch Harvey-nickel steel, running 2/3ds the length of the ship was also comparable to her European contemporaries. The weakness of the class was their low freeboard, small coal capacity which limited their endurance and only moderate speed. Even so, Oregon, the first battleship built on the Pacific coast at Union Iron Works in San Francisco, California, earned fame during the war for her 14,000 dash around Cape Horn to join the Atlantic Squadron blockading the Spanish squadron at Santiago, Cuba.  During the Battle of Santiago, she outraced the other battleships in chasing down Cervera's doomed squadron.

Hellenic Navy Armoured Cruiser

YS Master Pieces
1:350 Scale
Full Hull Model

Georgios Averoff is an Italian Pisa Class Armored Cruiser, was purchased in October 1909 with funds left to the Greek Navy for warship purchases by the Greek millionaire G.Averoff. The cruiser was named after the navy's benefactor. She was the flagship of the Greek Fleet during the Balkan Wars 1912-1913. The fleet under the command of Rear Admiral Paul Kondouriotis, successfully stopped the Turkish Navy from issuing from the Dardanelles and helped the army seize territory. On January 18, 1913 Averoff engaged the Turkish cruiser Medjidieh, four armored ships and 13 torpedo craft. Averoff met the Turkish squadron 12 miles from Lemnos and after two hours of gunnery exchange, the Turks retired. Averoff was refitted 1925-1927. On April 25, 1941 she escaped to Alexandria as Greece was invaded by the German Army. During the war she was a convoy escort in the Indian Ocean. The armored cruiser, Georgios Averoff is still in existence as a memorial at Poros Island, 40 miles south of Athens. (Conway's All the World's Fighting Ships 1906-1921)

The YS Master Pieces model of G. Averoff reflects her appearance during the Balkan Wars of 1912-1913.

YS Master Pieces Models

1:700 Scale

1. Georgios Averoff, Greek Armored Cruiser, 1912

If you have built an YS Master Pieces model and would like to have your model shown on the this web page, please send photos to: (


As modelers started seeing and building the beautiful 1:350 scale kits from YS Master Pieces, some asked, "When will there be a YS Master Pieces kit in 1:700 scale?" Now there is one, the Georgios Averoff, Greek Armored Cruiser, was the first 1:350 release from YS Master Pieces and now it is their first release in 1:700. The kit is different from most 1:700 models, in that it is available in two versions. You must decide if you want to build the traditional 1:700 waterline version or the one piece full hull version. One piece full hull 1:700 kits are something of a rarity because of the waterline tradition of 1:700 scale but also because of the added detail of the kit and difficulty of production. YS Master Pieces provides the choice.

The One Piece Full Hull Casting

Averoff4795sfsuppro.JPG (63520 bytes) Averoff4743endon.JPG (65200 bytes) Averoff4746pmid.JPG (51812 bytes)

The 1:700 version of the Averoff is amazingly close to be a perfectly scaled down replica of the 1:350 version. If you have seen the 1:350 model, you will be undoubtedly struck by the precision of the replication. It is only when the 1:350 and 1:700 models are placed next to each other that some differences are noted. The 1:700 version has been slightly simplified in parts count and design to allow for easy assembly.

Comparison of the 1:700 & 1:350 Averoff kits

Averoff4739tworams.JPG (77647 bytes) Averoff4740twoplans.JPG (53846 bytes) Averoff4741twomid.JPG (82582 bytes)

The fidelity of the 1:700 Averoff is not confined to only the hull casting. Many of the smaller parts appear to be exact half sized miniatures of the larger kit. What is remarkable is that no detail appears to be lost in the castings.

Smaller Resin Parts
Averoff4756main.JPG (79063 bytes) Averoff4757main.JPG (135069 bytes) Averoff4758masts.JPG (129860 bytes) Averoff4750stacks.JPG (152553 bytes)

The brass photo-etched parts consist of one fret. Because of size and complexity constraints, there are certain parts that appear in the 1:350 frets that are not included in the 1:700 version. One example is the ship's name brass plaques that are on either side of the bridge in the 1:350 kit are not present in brass in the 1:700 kit. Instead they are cast integral to the hull/superstructure. This is true with other details that were in brass in the 1:350 version, they are now part of the resin casting. However, take a close look at the extraordinarily high quality of the 1:700 fret. The three dimensional etching and consummate quality of the fret are evident in the photos.

It is strikingly clear that YS Master Pieces has the same commitment to excellence in their 1:700 kits as they do in their larger 1:350 scale sisters. Every component is of the highest quality, from resin, to brass, to instructions. The instructions come spiral bound just as those in the 1:350 kit. From the photographs, you can judge the high quality of the instructions for yourself. Each page is clear and well laid out. The instructions have many of the same drawings as those in the 1:350 kit but many differences as well.
