- My ballparker (OK- ball park) guess might be the cocking slide and joint roll- Col. Day is correct- main cause of minor Parker problems is usually dirt, crud, grease etc- How far did you dis-assemble your Trojan--

I have a later series 12 gauge Trojan receiver with many parts- all working- but no trigger plate or sears- by later style I mean- no recess in the receiver for the small doll's head barrel rib extension, and the coil top lever spring in the cylindrical housing- Let me know if you need anything by PMS- Now that we are allowed to sell Parker guns (thank you JD and the BOD) with compliance with BATF regs- we can also sell receivers, as long as they are shipped through FFL. Good deal all around--
