This is a interesting old Pistol in 22 RF. it reminds me of a pistol version of a schutzen rifle.
it has double set triggers and a mosquito fart will discharge it. I am interested if anyone happens to know anything about this type of Pistol... there are no manufacture stamps except the number 14, and also a proof mark of a crown with a G underneath it...see the picture. i have seen some examples of similar pistols that are definitely German manufacture. A name i found "langenhan" was one type very close in resemblance.

If anyone knows about this type of target pistol please let me know. thank you!
