Big old nasty 19th century electric motor crackling and popping its way merrily across the shop... LOL

It was at minimum from the early 1900's. Open gearing, open frame, open brushes, open switch contacts, riveted construction. Operator's pulpit hung under the bridge on one side, two drum switches of similar size to those on a street car next to the seat. The place was so old, the original railroad spur it was built on was serviced by Shays

Aside... you know connections etc... Sometimes here we are in 2 decades into the 21st Century and I wonder what my maternal grandfather born in the 19th century would think of it all. (He passed in the 80s... age unknown exactly.) He was a retired Polish American machinist who probably worked with some of that stuff when it was new and he was a young man.

Its funny. I recall writing him a letter asking him to make me a magnetizer demagnetizer coil like the one he used in his farm shop (after he retired). My mom refused to let him because it was "to dangerous" so he wrote me a long detailed letter explaining how to make it for myself. LOL.

I'm not that old myself and some of the things that have changed in my lifetime surprise me. In my teenage years we still had rotary phones and party lines, the TV was black and white and only picked up 4 channels ,6 if we turned the antenna just right.

Now the kids are making facetime calls and complaining about it if it isn't 100% perfect.
