I know mine's hell-for-stout. It might not be in the same class as a big Pacemaker or DSG, but it's big, heavy and has lots of iron where it counts.
To the OP: Yep, that looks like an L-1 spindle nose, pretty much identical to mine. If you ever find out for sure what the inner taper is, I'd be curious to know that, too. Mine's not necessarily any Morse I've been able to determine, and kind of buggered which leads to to think somebody may have tried to rebore it.
You do in fact have both miter gears on the carriage drive, which is interesting. What's also interesting is that somebody appears to have liberally greased the carriage gears- possibly due to the failure of the apron oil pump?
Apart from the difference in the headstock, it appears basically identical to mine.
Doc.
