What are the years Columbian made the rear jaw swivel...I have a really nice one in the barn and would like an answer for the occasional tour. BTW...took some time to get that pin out...and a sledge to get it moving again....but sure works great now. Funny...the BIL thought it was a piece of junk and left it in the garage in favor of his new swordfish 6 inch.
Congrats on the new to you swivel jaw!
