POUS ONE to Johnson Bar and Major 2
Welcome to the world of Uberti guns and as well, other Italian Manufacturers. I'll address Uberti first. Uberti does everything in "Runs." When Uberti is making a particular item in their catalogue, they do a "Run" of parts for that particular gun. That is the only time they make specific parts. When they (Uberti) run out of parts, you wait until the next "Run" of that particular gun. I once waited THREE years for a parts order to be filled.
YOUR next step, is to follow the lead of Johnson and Major 2 and chase the needed parts from the other sources. Taylors, Cimarron, Dixie, VTI, all those guys. Best of luck in your quest.
PS: Forgot to address your original questions. Yes, depending on the phase of the moon ... quite typical. Second question - SNAFU.
