Well from pictures I found online at
https://www.ebay.com/itm/315148732505 it would seem that the A model
just said "9114" on the front however the serial number label on the
bottom says 9114A.

Thanks, Paul,
I'm aware of the 9114A and B versions and some of the differences, but I'm
wondering whether my 9114 is identical to the 9114A.
Is it maybe like World War I which was just 'The Great War' until WW
II came along; same war, different name.
