Yeti what model is that. I had an old 50's era Milwaukee 660 that was similar, but enough different that I'm pretty sure it isn't one of them. Can't zoom enough to read the plate. 

Nice refurb.

Somewhere in back I have a few of the "Buck Rogers" type power hand tools of the 50's. I keep them around to remember what they looked like new.

Anything past 1970, 75 that is electric is a disposable POS in comparison. All power tools today are doomed to fail within 5 years or so. Most are only guaranteed 90 days as proof of that.
