RE: 12B19

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Thanks John.  Your information confirms my understanding that the B series
were incorporated into the W series.  That is, the 12B19 is essentially the
same as today's W12x19.

I checked on Ebay to see what older manuals are selling for.  I saw
different publication years within each edition:  '50, '56, & 59' for the
5th edition, '65 for the 6th edition and you're showing '63.  Could that be
mupltiple printing of the same editions?  Or were there interim updates?

David
