I have 2 of these, model 629-2e. Serial Numbers BEE5xxx. I bought them both new back in 1989. They cost $379 each then.

The "e" designation was for an "endurance" package that beefed up the ability to handle hotter magnum loads. Every model after that, i.e. -3 onward, included the modifications.

BTW: mine came without MagnaPorting, I added it later on both of them.
