Daisy Model 990?

[Star1pup]

My wife came home from a garage sale today with a Daisy Model 990 that she bought for $5. It is in like new shape and is a very interesting gun. It can be used as a multi-pump or CO2 and uses either BBs or .177 pellets. I can't find anything on this gun via the Internet and wondered if any of you have ever heard of it.

BTW: I pumped it up 10 strokes and it shot darn well with pellets. According to the manual it's supposed to do 660 fps. I might shoot it over my chronograph just to see if it will. It should be fun to play with and maybe put fear into the hearts of the chipmunks who chewed the wiring in my boat trailer.
