Bill, looking at your numbers made me hunt up my Serial Card again - copy attached.

I had always thought of mine as being a 'Pearl Harbour' period lathe, but now, on second look, I interpret the card a bit differently.

It was rec'd at the agent's warehouse - Cosiger Machinery Co, Dayton, Ohio, on 9/10/1941  (only roughly a month earlier than yours, so mine was 80 last month!)

It stayed at Cosiger for 3.25 months until it was dispatched to The Quartermaster, War Dep't Air Corp, Planehaven, California, on 12/19/1941.

Part of the problem was we read the dates the other way round down here in NZ. We go Day/Month/Year.

So, it must have been manufactured late August/early September 1941.

It is an 8187AN, so, also a Toolroom model, with a 4-foot bed.

It was just the basic machine when I purchased it, but I then spent 7 years searching E-Bay & corresponding with SB Lathe forum members and have managed to purchase all the items it would have had when originally built, including all the 5C collet gear, plus the complete metric transposing set and large-dial taper attachment & telescopic screw from Ted.

The gearbox was fully rebuilt by the 2nd owner (a toolmaker) before he passed.

He also incorporated a lever-action clutch into an enlarged UMD countershaft driven wheel as he screwed shafts for large building clock assemblies with it.

Just nudge it with your left elbow and everything stops!

He also built a very substantial steel cabinet to mount the lathe on.

I purchased it from his estate through a family connection.

Cheers,

Tony
