Is this a heavy 10?

Hi All- I was given this lathe 4 years ago by my stepdad whose had it since the early 80s. Its had a tough life as it was in a local high school for a long time. I’m finally getting around the cleaning it up and making any necessary repairs. A friend more knowledgeable than me thinks it’s a heavy 10 but is unsure of the exact model. It’s missing at least one ID tag. I think based on the serial that it was made in 1937. Id appreciate any help with ID and DOM. Happy to take more pics if needed

The tag on one of the covers says 'Swing: 11". While it does resemble a single tumbler heavy 10 it looks to be a lathe of 11" swing that predates the heavy 10? Poking around on the internet there are 11" lathes that visually resemble the heavy 10, as does yours.

What is the spindle thread? Threaded spindle on heavy 10's were 1-7/8 x 8tpi or 2-1/4-8tpi. That spindle looks smaller than 1-7/8 but the photo may be misleading.

Which is on the "Series O" 11" in catalog 94

Here are the later 11"

I was going to say wide bed 9" but the tag that says that the swing is 11" pretty much makes it an old 11" lathe. It potentially could be quite a nice machine.

Plus, a heavy 9 has the same spindle thread and ID as a 10L.
