Len said: "This is probably the nicest specimen of the Haenel Model 28 pistol that I had ever seen, and was thrilled to have been able to add it to my collection."

Haenel Model-28 - cocking arm torsion spring fix

Thanks to Guy and Jim for these pics of a modern replacement spring that keeps the cocking arm pressed up to the piston so it does not fall out of the cocking slot.

Haenel expert Bruce Jr says "to date there are still only 3 long barrel 28s known at this time.  #10086, #18286, and [the one pictured below] #18427 which is the only known boxed example."

Haenel Model-28 (police markings?) 

With thanks to Steve.

He said on the airgunbbs.com: "Always read that there is no proof that the Haenel 28 was used for Military training. How about a Haenel 28 with German Police markings? See the butt with marking “lb/sl”. On a website on German gun markings this is the code for German Police L.B., Berlin. S.L., Lueneburg district. Plus the number put on the grip? "

Eddie said purely from a metalworker's point of view: "The butt stamp in the metal looks like a block stamp to me, ie. not separate letter stamps, these are hard to get a perfectly even impression with by their nature (have used them 100's of times at work), and often one side / one end will be more pronounced, the temptation then is try again, which often goes wrong and you get a shadow impression, or again, because of their nature the first impression is on the faint side

Also, not the easiest place to stamp a pistol and support it rigidly, unless maybe the grips were removed and butt placed over something (if indeed a void like a Webley for example), so that would compound the problem."

Steve checked with experts on the Luger forum and said: "The guy who wrote the book on police Lugers and administrator of the Luger Forum:

'Could be police, but I don't think so. Shooting clubs were all over europe - I'd be more inclined to think it was some kind of club, or even factory marking? i.e. factory club or usage'

Another post says Unit markings weren’t lower case."
