I had an eBay vendor renege on a sale, so I had to hunt down some parts I need elsewhere...I'm waiting for parts from three eBay/GB vendors, a Brownell's order, a Numrich order, and a Travers tooling order. Backorders galore!
I managed to get the front sight dovetail cut, and milled the 'scallops' for the rear sight. Not quite like the Luger artillery, but 'good enough'...
Next I need to drill out the Luger rear sight blade & base for an inch pin (no Metric available) and drill a dimple for the re-drilled base setscrew (inch again, no Metric available).
For all practical purposes, the barrel itself is done. I do need to mill a front sight blade and press it in place, and then mill it to shape. That will come next.
