Groups,

I won't waste time explaining why a problem with our large Xerox 
printer/scanner/copier today led me to audit changes in subject manual but I found an 
error.  The 1955 change on page 7-18 either should not have been made, or 
was incomplete.  The change involved the terminal counts on Terminal Boards 
272 and 274.  They were correct as shown in the earlier AN 16-40BC224-2 and 
the earlier yet AN 08-10-180.  While it is possible that Belmont Radio Corp.'s 
original internal assembly documents might have shown each of those 
terminal boards with the opposite sequence number, none of those documents still 
exist and the manuals as originally written were internally consistent.  The 
earlier parts list, photographs and drawings all agree as to which TB had 14 
and which had 32 terminals.

Over the past 15 years, I've sold several copies of T.O. 12R2-3BC-112, 
mostly AFAIK to people who were members of one or more of these lists.  Plus 
others may have originals or copies from other sources.  If you have a copy 
(and care), go to page 7-18 and change the terminal count on 272 to read "32" 
and on 274 to read "14".

If you have a copy of TM 11-692E (I don't), check and correct if necessary 
the parts list in it.  I don't know that it's wrong but it was also 
published in 1955, the same year that the erroneous change mentioned above came out. 
 And if it is like the other TM 11-692 volumes (some of which I do have), 
it is just a reprint of the AN or T.O., with a new cover.
