Firstly, have your Panther G & it's a great kit (my only wish is for a set of steel resilient wheels for the very late models) my question is to whether the standard 'bayonet' type method for attaching the turret to the hull is the best way to go for a gaming model.
Gamers, unlike scale modellers, tend to rotate the turrets on their vehicles - in fact most of the WWII game systems I've seen (Bolt Action, Secrets of the Third Reich etc) have turret rotation & armour facings as part of their mechanic - & herein lies the problem. The standard scale model type attachment tends towards the snug - particularly after some paint is applied. This can easily result in damage to your meticulously applied paintjob or even a turret that is impossible to rotate.
I would suggest that you consider the method by which resin vehicle manufacturers fit their turrets - an indent in the hull with a corresponding large diameter peg on the turret base - both of which could have a small recess suitable for a magnet (as present in 15mm Flames of War tanks - for subsequent releases.
Looking forward to more of your excellent kits, (particularly the 251 & Stuka Zu Fuss variants) keep up the good work!
