Identifying a World War II Era Haenel Handgun: Seeking Information

Question
I recently was given a hand gun that belonged to my grandmother. According to the story, she carried it during World War II while she was stationed in Europe as a nurse. It is a small, heavy hand gun that has the following writing:
          C G HAENEL SUMLSCHMEISSER'S PATENT

The other side of the gun has the numbers 3590(the last number could be a 9).
I would appreciate any information you might have on this gun. Thank you, Bonnie Wallace  

Answer
Hi Bonnie,

The C.G. Haenel Co. was located in Suhl Germany and was established in 1840. It was not until 1921 that the company began to manufacture semi-auto pistols. This was after Hugo Schmeisser was hired as the companies chief engineer.

There were two models of this pistol that I'm aware of. The model-1 that was 6.35 caliber with 2.48" barrel. It had a six shot magazine and weighed 13.5 oz. The left side of the slide was stamped "C.G. Haenel Suhl-Schmeisser Patent. The grip panel was marked "HS" in an oval.

The Model 2 ...... was the same design but only had a 2" barrel and only weighed 12oz. and had "Schmeisser" molded into the grips.

The model 1 in "good" condition has a retail value of $225 and the model 2 in "good" condition a retail value of $250.

I hope this helps and thanks for the question Bonnie.
