Jeez, I feel old.
My first was a Form One back in '82. A MkII with a hybrid 4" ported barrel, then a 8 cup matrix to the end, about 7" overall. It gets cleaned out every year or so, the guts go into a Chem-tool bucket for a day or two then a water rinse, back to like new.
The action is louder than the report, and using my thumb to hold the bolt closed, well, I make more noise spitting.
I need to refinish the old girl, she is getting a bit too scruffy looking. Maybe Duracoat this time, blueing is just too much work for me now. I have a pair of those real pretty wooden factory grips for it...
