my bil of over 50 years recently passed away and his wife(my wife's sister) gave me these two revolvers. One is an Iver Johnson "Sportsman", mod. A524, 4 3/4 in. bbl. SN 57xxx. Would like to determine year of manufacture. appears to be in new condition, cyl. locks up tight in battery and each chamber times up real well. trigger is about 4 lbs. I think I have a dandy little plinker here. The other is of unknown manfacture, a SA with 22lr and 22mag clynders. 5 in bbl. under bbl says Germany 261xxx, SN also in front of trigger guard. on one cylinder "22 magn Germany" the other, nothing. on the bottom of the butt, "LA"s DEPUTY". any info on this one?
