Thanks Neil, Michael and Chris,
I'll reply to each of your messages chronologically;
The effects of the shading have been progressive via a few models namely the Dragon T-34 range which I will show here at a later date. (need better photos)
Although the Braille Battlefield Campaign is awfully tempting, I am trying to clear the half-finished hangar of kits namely some Airfix Braille scale Spitfires and a solitary Focke-Wulf.
Do not despair however as I have within reach more Dragon kits and oddly enough they are all German starting with the Tiger 1 Initial Production with two turret cheek bins, a Panzer IV F2(G), a Jagdpanzer IV L/48 early production and a Tiger II with fallschirmjager (Ardennes edition).
The track sag fortunately was not difficult to achieve, a pair of round nose pliers and a pair of mathematical dividers did the trick.
I tried to join Missing Lynx but it appears that the site no longer admits new contributors despite registering.
Cheers
