Can someone confirm I deciphered Catalog number and Serial number correctly?

The other day the boss overheard me talking about my 1931 SB Jr. and 3 other South Bends I saw at a nearby auction. I was there to buy 6 double door cabinets.

Anyway I had mentioned my lathe is now 87 years old. We have a South Bend and a Logan sitting in the corner doing nothing. The boss says so which lathe is older mine or the shop one. I said mine and told him the shop one is from the 50's or 60's.

Shop lathe: Catalog 670A S/N 28329KAR7. Model A, Light 10 with Quick Change Gear and friction feed apron. Horizontal drive with regular spindle hole 11/16", Standard swing. Didn't really understand what the 7 means.

I came up with a date of 1951/52, correct??

Thanks,
RF


So the 3 auction SB's were very dirty but well tooled: Model A CL670A with cabinet, Model A CL3137AB with cabinet: both sold around $700. Model A CL155 with a 12" bed S/N 8868HKX12 with 2 Phase motor, yes 2. Sold for $300.00 Several Bridgeports were also 2 Phase.

Looking at Steve Wells old serial data base, here:

I would say 5 digits followed by the letter "K", would put ser# 28329KAR7 at 1972. K's in the 50's were still 4 digits before the K.

Thank you for double checking. The boss will be surprised, he was thinking 40's LOL

Just don't run it! It's missing the spindle oiler cup.

I don't know the history of it but someone also wiped out most of the teeth on the bull gear and back gears. It's not in use.

Serial numbers on the Yahoo South Bend Group

1/29/1971 15560 KKR
7/21/1972 30730 KAX 10K x 4-1/2', Model A, Catalog No. CL670-RG, 12- speed HMD Bench Lathe, Gap Bed

So yes, between '71 and '72...

OK, thanks for the info.
