The above image I think is the Kerner-Anson & Deeley design, or something similar, with sort of what looks to be Merkel style pipe reinforcement. I'll have to check my notes or the source. About the only way I can think of to differentiate between the E. Schmidt & Habermann & Greifeldt, unless the mini-clamshell frame side reinforcement is different between the makers, is that Greifeldt had a unique safety that was akin to two "L" attachments one reversed on top attached to the trigger slide and another inverted and reversed that mates to the top one making a unique safety.
