Crosman 1100 box.
Crosman 1100 shot shells.
Crosman offered two different styles of target for the 1100 - a two piece, yellow plastic target that simply broke apart upon being hit, and also, downsized clay targets, which are quite rare to find due to their fragile nature.
Crosman Model-1100 Trapmaster CO2 shotgun reseal
With thanks to Louis.
He says on the American Vintage Airguns forum:
"The Trapmaster was made between 1968 and 1971, so it's no wonder that the o-rings were flattened and the valve seal was hard like a rock. I had to burn it out.
A seal kit is on its way (off the bay). I might be able to finish the reseal by modding a Crosman exhaust valve seal that I bought from JG airguns to reseal my 105.
It appears that the dimensions are correct, except for the hole in the middle; it needs to be enlarged.
I think it would be better to remove the steel pin in the middle, but I guess it's pressed in. I have a feeling that I will be sending this part to forum member Lawrie in England, "The King of Seals".
Heather of JG Airguns has kindly answered my question about the difference between the 150-54 and 350-27 seals, which looked the same to me: they are in fact ever so slightly different. 350-27 is a fraction smaller, and perhaps made of a different material. Thank you Heather, always a great pleasure to deal with her.
I think I'll be ok with 150-54 seals instead of 350-27. A bit of a tight fit, but it will work.#
For future reference: this needs to be assembled first before putting it into the left side of the breech.
This afternoon/evening I finished resealing and re-assembling the Trapmaster.
It works! I'm pleased.
Time will tell if the valve seal is good.
The "standard" 150-54 really is bigger than 350-27. With 150-54, the part doesn't slide into the cylinder. With 350-27, it does.
I had some slightly smaller o-rings than 150-54, and they did the job.
I have set the hammer spring preload quite low. Will test with higher tension.
Now I am getting 380 ft/s with the red Crosman shells. About 15 ft/lbs?
I have understood that they can do 500 ft/s."
