<DIV>Close</DIV>
<DIV> </DIV>
<DIV>Very good on the list. Alex would be close to giving you the daily
double.</DIV>
<DIV> </DIV>
<DIV>All plain machines became automatically the A model when a B model was
introduced. </DIV>
<DIV> </DIV>
<DIV>I am not aware of a TR-3 B version. So that one we need to ask
more about. Would this be the version that was after serial number 3150
that included the Line Lock module? After 40170 for TR-4?</DIV>
<DIV> </DIV>
<DIV>The TR-4 HB was not a factory delivered model. A TR-4 HB was done in
the field or as a refurbishment. on a trade. </DIV>
<DIV> </DIV>
<DIV>It was the TR-50 if done at the factory. </DIV>
<DIV> </DIV>
<DIV>The TR-22 HL was never delivered so that one bites the dust on the
list.</DIV>
<DIV> </DIV>
<DIV>The rest of the list is pretty good. Got every one of the
versions. </DIV>

<DIV>So we have not had any takers on the subject.</DIV>
<DIV> </DIV>
<DIV>So since we had a great discussion about the TRT-1, here is the answer
for that series.</DIV>
<DIV> </DIV>
<DIV>TRT-1A</DIV>
<DIV>TRT-1B</DIV>
<DIV> </DIV>
<DIV>There was a C added to the end if it had the color rack added.
The A version had a number of different layouts. It was the very first
machine that RCA really mass manufactured. The layout would change and
the servo amps were a number of versions. The design by the B model
was stable.</DIV>
<DIV> </DIV>
<DIV>Now there were several other accessories that were available.
Solid state Capstan servo that was the Switch lock. Then Pix Lock that
did the H lock. Finally a monochrome ATC system.</DIV>
<DIV> </DIV>
<DIV>So does anyone else know the other models?</DIV>
<DIV> </DIV>
