I got this today but not sure of the maker, to me looks Militia like but no markings visible anywhere.
It's quite like my side push button one which only marking is "Made in Germany"

It has an octagonal to round .177 rifled barrel, a tap like barrel latch up/release, the underside of the barrel and cylinder are both stamped 95, has metal butt plate and chequering at the wrist and I'd assume between the wars.

At the left side of the breech block there (in my mind) might be a faint signs of a name (see pic) but it could be wishful thinking on my part and possibly just marks from the original machining.
There may even be something on the cylinder but I don't want to sand back to bright steel obviously.

It would be nice if someone recognises the model/maker. An idea of value would also be useful.
