Thanks. I know the ladder type sight is on the barrel. I have seen the tool for sight adjustment on GUNBOARDS. I think I will not buy this one. The replacement of the toggle sort of turned me off. I have a friend who I am trying to convince he wants to sell me his DWM 1923 COMMERCIAL, 7.65 mm. marked GERMANY on right side of slide
It's a little rough, but looks to be original.
Thank you again for your time and information.
