I have/had 21 and 22 in half,full and the rare 3/4 stock.The 3/4 was not an import,however I have two,one in 30/06 and 7/57. I just sold a 21F in 8x60. I've no standard on the dovetail mounts and round tops,I've had both with a date stamp of 1948.
How's that for mixing up the info...I'll try to gather a few photos for you.
