Crosman 180 - hope it's repairable!

First post, guys...hope it's in the right forum.

Can anyone recommend a repair source for this .22  co2 "Pellgun"?
Crosman 180  (Couldn't find any Serial No.)

I have the parts list and this is what it will take:
1 Seal Kit (Consisting of:
  1 150-060 Valve Stem Assy
  2 150-054  O Ring
  1 130-033 Breech Bolt O Ring
  1 180-057 Breech Gasket
  1 150-28 Exhaust Valve O Ring

Additionally,
1 160 20  Rear Sight
1 180-29 Spacer
1 180-29 Bolt Knob
1 180-22 Strap Screw

Not interested in a full restoration - just want to get it functional again (without leaking co2)

Thanks for your help.

I have never heard anything but good stuff about Alan at ABAirgun http://www.abairgun.com/index.html when it comes to Crosmans.  

If it can be fixed, he is the man!

Thanks!  I appreciate your response.
