I don't know if you'd find that much rust in the interior? There seem to be a lot of rust streaks, and thet probably wouldn't happen in an active vehicle.
I totally agree with you there Karl!
Also, I think you should think about painting the sights on the gun? I've usually sen them in black with some steel drybrushing?
OK....you know me, so here is the M12 panoramic Telescope
Dark green with a rotating black scale, black eye cup and black veriner . The front of the head would be a mirrior/silver (head in the photo is facing away)
A nice job on an older kit though!
For Sure!
