Not so sure it's a refinished Luger, with the exception of the non-matching toggle train. It could just be the light..

I would consider finding a #35 BYF toggle - and if I should sell it, notify about the replacement. The bakelite grips alone is worth quite a bit if original ..but on the other hand, the crime scene-photo would lower the value for me
