I have seen the portable one displayed.  It was a military unit that  was 
sold to the public.  I was told somewhere that the original military  one was 
a Octo-plex unit.  I have vague memories of someone previous  mentioning 
the model and working with it.  So we have to assume that it was  sold.  

Any way this has been an interesting discussion.

Hello  Chris,  

Well, it was s stab anyway. You are the expert, not me. I only offer the  
following:

In the RCA New Look Price List dated March 1, 1967, the TR3B is listed at  
$22,500.00 I would surmise from this that the 3B was shipped from the 
factory,  as opposed to a field upgrade.The 1966 sales catalog does not mention a 
3B,  just a 3. Additionally, the same price sheet lists a TR4B for $34,900. 
The 22D  is listed as $59,500.

Thanks for the clarification on the A model assignment when the B model  
came out. Likewise, the TR-22HL correction. Most interesting is that the TR 50 
 was a TR4HB if coming from the factory. 

Do you have a TPR-10? That one is elusive. The competitor to the VR  3000.

Regards,

David

Very good on the list.  Alex would be close to giving you the  daily double.

All plain machines became automatically the A model when a B model was  
introduced.  

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?

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.  

It was the TR-50 if done at the factory.  

The TR-22 HL was never delivered so that one bites the dust on the  list.

The rest of the list is pretty good.  Got every one of the  versions.

around many RCA's, all humming away under one roof (over 25).

So we have not had any takers on the subject.

So since we had a great discussion about the TRT-1, here is the  answer for 
that series.

TRT-1A
TRT-1B

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.

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.

So does anyone else know the other models?
