Jon,
Thanks for pointing this out.
I looked on my original list and it's the same. If however you look
at the list 1941 finishes at 1549 and '42 starts at 560 I think this
is a typo and should be 1550 because if you then look at the finish
of '42 it's 2943 whereas the start of '44 is 944. They have obviously
missed the 2 off the front.

I checked the two Adcock and Shipley bridgeport I have and they are
listed as J350 and J1695
The J350 is a 2J variable speed with the electronic power feed that
sticks back at about 45 degrees and has chrome ways.
The J1695 which I though was an earlier machine is identical except
that it has the mechanical gearbox power feed. The J1695 has a
varispeed head on it numbered JB 13678.
I think I'll try A&S to see if they have any numbers for the licensed
machines.
