    As a riflesmith that owns two older American iron lathes- one a SB, the other a Sheldon, I'd say it's way overpriced- though there's likely someone that'll pay that price or close to it.

    There's some guys 3D printing various SB gears and selling on Fleabay.
    Might be enough demand to approach them about it.

    Nice man cave. I could never have a setup like that as a working shop as it would be trashed in a matter of days, but a great home for light/rare machine use.
    Good luck with it.

    No wear ridge near the headstock is certainly a positive indication. Overall, doesn't look as though that machine has seen heavy use and neglect in a production shop environment to me.

    1-3/8" spindle bore.
    Short headstock.

    Makes them attractive to riflesmiths.

    Nothing special about the spindle thread.
    Skinner was a good quality chuck, should serve you well assuming it's not worn.
    Pull the screws and jaws, clean em up, lightly oil and put it to work 😊

    You should write a book.

    Did you remove the bearings to check condition of them and the spindle for wear/scoring?

    Ditto to all the above- including the spindle wicks. The good thing about SB's- esp. the 9's- is that they were prolific and well made. Still plenty around getting worn/parted out and most parts can...

    Never knew the 10L was ever made with anything other than 2-1/4"-8 with 1-3/8" bore, with the same OD.

    Might be worthwhile to to replace the oil in the reservoirs even if leaving the wicks/spindle in place.

    Calibrating Thread Mikes Without Standards?

    Nice score, very light wear.
    Be sure to flush all the gears- grease is a bad idea on lathe gears. Traps and holds swarf and accelerates wear.
    Stick with recommended viscosity oils.
