Andy, you're working off an old copy of the TV Guide...my time slot for updates now is variable and no longer tied to Sundays! I'm finishing up my current MBA class (Business law...always a fun topic!) and then get a 6 week break due to already having credit for the next class in the program...so you might see a temporary spike in posting/output over the month of March as a result.
Mike, always glad to get your input on the details! The series of photos that I posted for the gun were "auto corrected" for lighting and color (something I virtually never do with photos) because I was struggling getting the details to show up properly once the gun was built and detailed on my monitor. The correction "brightened" the photos and made some things (like the breech) appear shinier than they really are and also made some things (like the gun sight) appear darker. Go figure.
The details "in hand" matches what you describe, a dark aluminum color and not chrome for the breech and metallic highlights/wear from the dry brusing on the gun sight. DML molded the top facing aperture on the sight extremely tiny for some reason and, while a clear part that would make it possible to show the reflective detail you mention, I was unable to keep the aperture clear when I painted the rest of the sight and that was lost. The eyepiece on German sights has a rubber cup and its drilled out with a spot of silver on the inside but only visible from a specific angle that I didn't capture in the photos (probably drilled the eyepiece a little too deep!). I am going to go back and detail a couple of the knobs on the sight now that I've had a chance to do some research, nice catch.
On the recoil slides, I weathered theem the same way I do bare metal contact surfaces for road wheels and such and wanted a dull appearance. My build isn't going into a dio or including a crew so it's conceivable that the gun hasn't been fired for a while, hence the look I went with.
Tread, I think Mike's obsession is a manifestation of the little boy in all of us that is fascinated with things that "go boom". That and the fact that he's an engineer...talk about your "explosive" combination! I always appreciate yours (and his) comments!
