Hi Rich, hopefully, Olle can jump in here as he cuts most of my dovetails, Or Don, either does a great job...
The sight blades I just had manufactured were take directly fro the original print and then reconfigured to compensate for the additional dimension height needed?
So, I sent 3 sample original barrels with perfect or un-used front sight blocks / dovetails..
Also sent the updated print from the Luger 1913 blueprint drawings
And three original uninstalled standard 4" barrel sight blades... They did all the retro engineering and modifications, (tooling fee, not cheap!)
They are perfect in fit and form... not going to last long... Best to you Rich, til...lat'r.....GT....
