Andy, you can follow the above steps and post pictures; or if needed, send them to me.
it sounds like a mismatch to me, as navy lugers are 6 inch or 4 inch barrels; plus the 8 inch was not matched up with a S/42 toggle. A S/42 would not have a wood base magazine, but be aluminum.
Is it all matching?
Is it all the same blueing?
