I hope the clickbait title worked.
Some history of the real submarine first.
Y-1 Katsonis
Y-1 Κατσώνης was a Greek submarine active during the Second World War. The submarine was built at the Forges et Chantiers de la Gironde shipyard, in Bordeaux between 1925 and 1927, and commissioned into the Royal Hellenic Navy on 8 June 1928.
More info and service history:
Some photos:
The model is a preproduction 3D test print that I was asked to build. Unfortunately for me and the designer there are no official drawings of the submarine and he had to use photos as reference for designing the model.
This is what I was given:
Five hull pieces with no surface detail like rivets, panels etc
The sail, the main gun and a machine gun and a couple of torpedoes.
There were some more small pieces included like the hatches, navigation lights and hydrophone and some bitts.
After some digging I discovered that the two submarines built for the Royal Hellenic Navy were almost identical with a type built for the French Navy, the Classe Circé (1925)
except the main gun, which in typical Greek fashion, instead of using the typical French gun of 75mm a modification to the design was made and the QF 4"/40 MkXII mount was installed.
My biggest issue with the whole project the was the lack of information and reference. So if by any chance someone has the drawings of the Circe class submarines available I would appreciate if I could have them in any form.
I started by assembling the hull and trying to figure out how I could add whatever detail possible.
There was a fret of photoetch decking supplied but only had the deck plank lines lengthwise.
As one can notice the anchor detail is very crude. After some digging I found that I had downloaded at some point in time a collection of plans that the French Naval Museum had made available. This collection included some plans of a 1500 ton class that was designed and built in the same shipyard at he same time. By examining whatever available photo I had and the plans I noticed that there were many similarities in various details.
For example this is how the anchor should look and be installed:
Or this is a drawing that shows the setup for the deployable radio antennas
More work was done on the model
I had to break the sail apart because it was bowed and this helped me set it straight on the deck
The front rudders were corrected using this as reference
and more details were added where possible
I tried to find a way to add the ships name at the sides of the sail so I started by supergluing some 0.75mm masking tape.
The paintscheme was decided to be the one the submarine had prior to the start of the Second World War, as it was immediately painted full black when the war broke out.
The model is about to be finished, some riggind is left and of course some corrections to the paint details, some surface light sanding to get rid of any particles and a final varnish.
Next post will be the finished model, thank for looking.
