I have been thinking about the assembly of the main shaft and the carrier block, rear plate with barrels and the front plate. I checked my drawings and found the problem is I\'m missing 48-07 and 4800 1 of 3 :shock: I have one numbered B48-07(Sight - Fornt & Rear). I have all the ones from 48-01 through 48-30 except the one previous mentioned. The latest date I can find on any drawing is 2010. Is there a newer version? I hate to rebuy the whole set of drawings just to get 2 of them. Can Anyone help?
