Crosman Mark 1/2

Anyone know of interesting sites on the web for information on the Crosman Mark 1/2 guns? I just got a Mark 1 in good shape and like to gather good information on all my airguns. Tom Gayloard's blog at Pyramyd has some good information that I've already seen.

I haven't found much here at Airgunnation but I know there are a lot of people out there with the Mark 1/2 guns.

You can also download a complete Crosman Mark 1/2 shop manual. Mark 1 and 2 s are one of my favorite plinkers along with a Crosman 600 and S&W 79G. I've purchased all of mine at the NC Airgun Show in Hickory,NC. I usually hand them off to Sue Smith of Airgun Hobbyist who does a great job resealing and tuning these old CO2 pistols.

@ajshoots-great informantion.
