The top one is indeed the anniversary model once more made to look like my 760 variant 1 which was dated, " 60" on the pump tube endcap. They were dated that way on the ones made
before July 1975. The "60" meant June 1970. After July 1975, the first 3-4 numbers of the serial number is the build date. Rather odd that an, " anniversary" model has the later plastic receiver and bolt? The metal receiver and brass bolt should've been used. They were self-cocking back then as well. The ones with the plastic receiver and plastic Remington Nylon 66-like bolt are manual cocking. That is to say, it isn't cocked until you pull the bolt back to load it.
The bottom one is a variant 4, like mine, built January 1978. A year later than mine, built January 1977. What's the odds of that? The first three digits of the serial number are the build date. In this case, "178", which normally would be expressed as "1/78". The 760 variant 4 likely has the full-length smooth-bore barrel like mine too? But it shoots straight, so that's okay. Just don't shoot BB's through them and the barrel will be/stay more accurate with pellets. They seem to like the JSB Exact Express 7.87gr, H&N Sniper light 7.5gr, & Beeman Silver Bear 7.1gr. Which makes sense, as they were tested with 7.9gr pellets! Steel BB's aren't good for those old, " soda straw" barrels. And thanks for the kind words Stefanjan. I love the vintage Crossman's! I've seen like-new, never fired or very little 760's go for as much as $175 on the auctions. The 760XL & 761XL models with the brass-plated receivers, rifled barrels, & unique stocks for as much as $275!
