My Crosman Trapmaster 1100 .380 caliber Co2 air shotgun was in excellent condition except for the barrel band (the upper left portion was broken off).
I found a company online in Illinois called JG AirGuns who manufacturers every single part for many vintage AirGuns, including the Trapmaster 1100, and so I ordered one to complete my 50 year old Crosman!
The barrel band cost $45 US plus shipping.
My lovely 50 year old Crosman Trapmaster 1100 Co2 shotgun is now in "excellent" condition!
The barrel band was quick and simple to install.
This airgun is almost too nice to take outside shooting ;)
This is a photo taken by Mr. Marvin "the airgun guy" of the Trapmaster 1100 that I later bought.
It is truly a beautifully put together airgun!
These are my photos of the receiver:
