Wow, have not made these great pistols in over 20 years.  What exactly do you need to know?

This booklet will give more info than you probably want or need:

I should have known dean had a booklet on this crosman. I know a lot about dean I have 3 of his hard cover efferts (I have one of the hardcover 160 rifle books) his history of crosman and the book on the early crosman rifles as well as the 160 book. I also have a booklet on the pneumatic pistols of crosman from the 105 through the 1377 new models.
Since one of the Mark I's in still in the box I am hoping for an origional owners manual. the second has no paperwork but is 95+++ condition as well I made a fantistic deal for both guns. I could sell 1(the unboxed version at that!) and keep the other and  make a profit on the set.
This is the one crosman I know nothing about so a basic operation info would help like where does the co2 go how to load the pellet and how does the gun cock I do know it should have some adjustment screws but wont know for sure til the guns get here (soon awaiting UPS) thanks for any info you cn start me off with is appricated. thanks

Unscrew the knurled knob at the bottom of the grip and insert a CO2 cartridge.  Don't have a gun in front of me and can't remember which way it goes, but the neck of the cartridge should face the piercing pin.  Then screw the knob back on - just finger snug, not tight.

Depending upon which model(s) you have, you next either flip the lever (if it has one) on the bottom of the above knob or tap the bottom of the knob (if smooth contour) on a flat surface to pierce the CO2.

Bolt is opened for loading pellet by turning the knob at the rear of the receiver (I think its a quarter turn) and pulling it rearward.  Load pellet and return bolt to locked position.

Cock by pushing the cocking knob(s) forward until it "clicks"  (note, first click is low power, second click is high power).  These are the knobs that protrude from both sides of the receiver.    

Older models had adjustable power screw on front of the frame (tensioned the hammer spring) and adjustable trigger.  

There is a good chance the seals are dried out and the gun(s) will leak CO2.  Tim at Mac-1 is the CR Mk1 guru.  Check out his LD conversion!

and both are in excellent shape way to good to convert to an LD or anything else. The good thing is both hold gas and shoot hard. And 12 ++ hours later they are still doing so. I think they are going to continue to do so for quite some time. these guns are already more accurate than I can hold but still a lot of fun to shoot!
Thanks for the info on opperations procedures.

Glad to hear they're "holdin."  

Mac-1 has a deal going.  If you sent him 4 Mark I's (or Mark II's), he will return one LD package.  What you send doesn't even have to work, just be complete.

I have picked up 3, but one is too nice to convert (still in the box).  So I'm still looking for 2 more (on the cheap).  Somehow at the last gun show I  passed on an in-the-box Mark II with an "asking" price of only $40.  

I'm pleading temporary insanity!

But even now the guys with juskers think they are made of gold. I am constantly seeing well worn Mark Is and IIs not even holding selling for $90 and up some to well over 110 for junk. The last gun I saw as nice as mine came complere in the box with a holster and a tin of pellets and a 5 box of powerlets probably all bought at the same time and never used. the starting bid on this gun was $210. Now admitedly I just got the gun but i got 2 of them for less than $140 both holding and shooting in excellent condition and I have 2 nib still in then wrapping crosman holsters coming for $15 each( a friend found a gun shop with a box of a lot of old crosman stuff still in the plastic selling for half price we over on the crosman forum cleaned out the store. I got the only two Mark I II holsters. There were some 38T and C holsters and a few others as well.
All I need now is a crosman 150 holster. I already have 2 for the pumpers the 130 105 and the 130s so I am good to go there. I even managed to buy a Desert eagle holster that fits my P1 P3 9N and it only cost me $8 shipped to my door!  I probably will need a holster for my Hurricane as well when it gets here as well. Oh well thats me I talk too darn much some say.
