A member pointed out to me that a 4" Luger front sight band + base would be too short for a 6" 'Navy' style barrel...So I guess I'll be making one from scratch...
I looked at Ed Tinker's albums, and Ed has a Navy pictured -
Unfortunately, Ed sold it. I can try to extrapolate the front sight base height from the pic...But if anyone has a Navy (or a repro) they could measure, it would make it easier!
Thank You!
In the meantime, I'm working on the front sight base/band blank...
