Clandestine Sciuridae
It's a .177 caliber and looks like this:
Are you looking to buy one ? If so, I have one (like new) I'll part with for $75.00
Many a bird, squirrel and rabbit feared the sight of one of those in my neighborhood growing up! Not sure what model mine was but it looked just like that except it had a smooth forearm without the checkering.
I have a .177 Benjamin from about 1972 that has had thousands of rounds through it. There is no telling how many birds, squirrels, snakes, turtles, etc. that I killed with that thing as a kid, not to mention the thousands of cans, bottles, and other targets. It was always, and still is deadly accurate within its range. Mine leaks a little while pumping now, but it'll still shoot yer eye out.
That's about the same vintage as mine. Mine leaks too; if you pump it really slowly, you get no pressure, but if you pump it fairly quickly, it will still hold a charge and shoots great.
I had a girlfriend that sounded just like the description you used for your 347
Sure do miss her!
