Treasure in the garage

We did soem clearing out in the garage the other day. We were digging out items for special uplift and the dump when I uncovered this wee gem. I have another lens for it up the stairs but I had absolutely no idea the camera was kicking about.

I'll need to download a manual from the interweb as the shutter release button doesn't appear to be doing anything at the moment at worst it might need a wee bit of servicing, probably not too much of a problem as the mechanics of it look quite simple.
