Interestingly this kit hull is in two pieces.
I am led to believe that MPC and Airfix had a 'special relationship' in the 70s - apparently MPC provided Airfix with their products -probably cars - and Airfix reciprocated with theirs. I do not know what products Airfix provided but it could have been 1/600 ships as well as the more popular 1/72 aircraft. If they did provide said scale ships then our quest may well be sated.
I have taken'control' of my grandson's 'Moskva' (purely for research purposes only????) and have quenched his current kit-building desire by providing a Revell anatomy model (self-build body parts) of the great white shark (Inclusive of an additional grandpop tale of dashed derrring-do and buckle-swashing that Errol Flynn would be proud of - incidently telling massive un-truths to Grandchildren is in the 'Grandfathers' Charter' - at least it would be if one existed!
As a bye the bye - these Revell anatomy kits are very good, reasonably priced and recommended.
Still, back to the issue in hand - I await the results of your scanning exercise with bated breath!
If we fail then perhaps ddp59 may be able to help.
Thanks for all your efforts,
Nick
