Sorry, I don’t know much about the 760 but you are correct on the manufacturers date. 

I do. I rebuilt one Jeff over on GTA gave me that was given to him by a friend out junkin' that pulled it out of a trash barrel. I collect and restore vintage Crosman's, & have 10 760's so far from June 1970 to November 2002. You can go to Mike Baker at Email [email protected] for NOS parts. Mac1 or Dennis baker at Baker air guns for seals and assorted small parts. Even Amazon and eBay fore seal/assembly kits. But be careful with those last 2. You can get burned by the cheap guys that toss a pinch of seals in a trial size ziploc bag. Here's video one of the restoration on the 760-D. 1 through 5, then a final. You'll have to look through my list of videos for them, as I rebuilt a trail NPXL1100 some 8 years old now for a friend in the middle of working on my 760-D. But it'll be worth it for you to watch every single step needed!

"D" could be something to do with the rifled barrel model, if yours had had bb;s thru it and you want a good pellet shooter you might ordewr one cheap from crosman.



Your part numb er looks correct.

I'm not sure what the letter suffix means? The only guy left at Crosman that knew retired a few years ago. I have two 760-B's, two 760-C's and one 760-D. All Pumpmaster's with the two B's the newest, for some strange reason? I don't think I've ever encountered a 760-A though?

760-B, NOS, Oct/01;



760-BRD, NOS, Nov/02;



760-C, 1/89

;

760-C, D/91



760-D, 4/98



This shows the differences between the letter designated models. But I have yet to find an adequate explaination of said letter suffixes? Some minor difference(s) internally I think? When I go to restore a couple of them, I'm sure I'll discover the secret for us all?!

The end of the barrel has teeth like an axle. the mount is pressed on. So you might have to use a tack hammer and a punch to remove it?

Hello, send an email to Crosman requesting help to date my 766 and they answered me right away, that may help.
I also leave the quartering they sent me.
I love this carbine.
a greeting

Hola, mande un correo a Crosman solicitando ayuda para fechar mi 766 y me contestaron enseguida, puede que eso le ayude.
Tambien dejo el despiece que me enviaron.
Me encanta esta carabina.
Un saludo

Being a 766, not a 760, makes it different. It's more like my 66AB Powermaster. The 760's barrel has those axle-like teeth on the outside of the end of the barrel inside the receiver. But it still looks to have that black plastic inner barrel mount (766-112) in the exploded diagram. In other words, your 766 has a sleeved barrel like my 66AB. AKA a barrel shroud.
