Jacobs 2A Taper?

Anybody familar with a Jacobs 2A taper? Based on the fat end
measurement, it might be a "2 Short", but I can't find any references
to 2A, and that's what is stamped on the chuck. Haven't figured out
how to measure the narrow end or the depth accurately yet.
It's a nice chuck, came free with the lathe, but the MT2-JT2A arbour
seems to be on permanent back order (or the vendor is pulling my leg).
Anybody know if I could use a MT2-JT2 arbour instead of "2 Short" or
"2A"?
Thanks,
Chris

The 2A stamped on the body of the chuck is actually the model number of the chuck. It uses a #2 JT mount, not the "2 short", so a MT2-JT2 arbor would be what your after.

"Made in USA" - these I can figure out. Half inch capacity too! :)

Jacobs actually made a 6A-2A model chuck, the marking "Taper" is to differentiate it from the threaded model. The taper is a 2.
