Dellos, did you find any manufacturer's marking on the revolver, ie, Uberti, ASM.,etc. The barrel markings are a German distributor's marking. I looked at your profile and found you are in Poland. Do you have any problems selling and shipping a black powder revolver to the USA? If not I would pay $300 plus shipping for this revolver. The Replica Percussion Revolver Collectors Association does not have this distributor in its collection (over 800 revolvers currently in collection).
