I have a Mitchell SS luger.
Pretty sure most everything is interchangeable with a German PO8. Mine is now fitted with a German sear spring and after a little fitting it works fine.My original one flew off at the range never to be seen again.
I have had mine since new and I have posted pics of it on the forum.
Have you gents seen the nice velvet bag and original black vinyl holster that was available for the gun?
They are really pretty guns.
