[Milsurplus] Change 1 to TM 11-800 BC-191-N

Marty & Group,

First, I found the T.O. 08-10-165 I was supposed to have.  Covers only 
BC-191-N.  Unfortunately, it did not shed any light on my main question, which is 
why the jump from -F to -N.

Second, I am beginning to suspect that I miscounted the number of Change 1's 
to TM 11-800 I had and sold all of them.  So if Don Merz or James Beeler are 
on this list, please check and see whether you still have the ones I sold you 
11 years ago.

Third, all models of BC-191 have two sets of connectors.  It took some 
digging but I finally found that blanket statement buried in the text in TM 11-800.  
The schematics in TM 11-800, TM 11-4017, TM 11-310 and T.O. 08-10-165 are 
misleading in that they only show one set.  But if you look at the "fine print", 
plus a photo in TM 11-800 identified as Bottom View of BC-191-(*) and the left 
end photo, you will see two different four-digit numbers apply to side and 
bottom connectors as well as microphone and key jacks.  The side mounted units 
are numbered 112n while the bottom units are numbered 117m (n and m do not 
match, either).  If you look carefully at the schematics in any of the manuals, 
you will see two four-digit numbers plus the SO-nn or JK-nn number next to each 
socket or jack.

Finally, what started this was that I was offered a TU-3-N for the 
MT-1518/ARR-41 that I listed here a few days ago for X dollars or best offer, plus a 
note that I was looking for TU-2, -3 or -4..  I was hoping to learn what the 
significance of the N was but maybe that will turn up one day.  I've decided to 
accept the swap offer on the basis that beggers can't be choosers.  I'll respond 
to each of the rest of you who responded with a non-insulting offer (there 
always has to be one in any group) after I crawl out from under the mountain of 
Susie's ebay sales from yesterday.

Oh, and AN/VRC-3 is the vehicular version of SCR-300 (BC-1000).  AN/VRC-1 is 
SCR-193 plus SCR-542.    The "official" transmitter model is BC-191-A.  Which 
is passing strange as the VRC-1 manual dates from 1945.
