Here's my 1:1 scale, Tail Boom Spitfire Mk.I, Ia, II spade grip. Recently bought of fellow LSP'er Junco. So far all I've done is clean up the gun button and brake handle then given them a coat of primer. For some unknown reason, I didn't take any photos of the brake handle, will include some next time.
Casting looks very good regarding pin holes/air bubbles. Slight miss match with the molds on the spade grip but nothing to worry about. All stamp detail is really crisp and will look good with a wash.
To give some idea of the size, I have included a photo with me holding the grip in one hand.
I have on order from Maurizio (Tail Boom) a canon armed Spitfire grip, rocker switch instead of button, as well as a early and later RAF gun sight. Early with oval glass and later with square glass. Again these are all 1:1 scale.
Thanks for looking
