I thought Sputnik was something the Russians shot up into space?

So Gerry and I are cruising the backroads of Lancaster- doing horse errands- which entailed stopping at every tack and harness shop in the area. We made a wrong turn, and ended up in the Noble Road Milking equipment driveway...and I read their sign. A sputnik?

So I googled it....and, this will shock you as it did me, there is nary a word on sputniks of the dairy variety. Maybe I'll try Bou-matic next ...
