Do I need to go there? Why is it every time I go to the shop there is another motor? Do they breed in the dark?

Typical 40s-50s models would be "HD25", "TD15", TD20" etc. Two letters + two numbers is typical. Unless there is a separate model / serial plaque, it’s going to be stamped directly into the case 99% of the time. BTW – Howdy friends, old & new! I was totally flummoxed when I couldn’t find the forum.. just figured out what went on with the server loss, and got re-regged today!
