Suggest you contact FAA folks. I think this answers the questions.

Noel, here is a saved message about TSO, with comments from the FAA guys... I
suggest you call either one , or both for clarification.......
IN response to my posting a question on the customer service line, and then a
follow up on 3-17-07, "When can I get an answer to such a simple question ?" ,
I received an e-mail from FAA:
An e-mail response from [EMAIL PROTECTED] on 4-5-07 @ 4:51:33 pm EDT:
Subject: Re: Are radios and/or flight instruments required to be TSO'd eqpt
for use in VFR part 91 antique aircraft?
(Incident: 070317-000004)
Response from FAA Customer Service Agent on 4-05-07 @ 04:51 PM
Hello:
"For this matter, you may contact the Technical Programs and Continued
Airworthiness Branch at 202-267-7242."
Which I did. :
I did find some of my written comments on the conversation with MR. Henri
Branting, FAA Engineering & Production, on a telephone call of 4-6-07 @ 11:16
am. He also advised I talk to Bob Moten, FAA, at 202-267-3813. However, I
believe Bob was out of the office. I do not remember talking to him later.
I remember Henri's comments form my notes: "TSO is a packaged approval for
installation in a particular aircraft"
"It is an option - makes it easier to get field approval of an installation .
in a TSO approved for aircraft."
If an aircraft type certificate includes language that requires a TSO
instrument/avionics, etc., then it is required.....
---as required in an AD
-- not required in Part 91 operations, unless specifically required in
aircraft Type Certification....
However, I think all transponders are required to be TSO'd.., and of course
in flying under instrument rules, I think TSO'd equipment is required..... BUT
not absolutely sure.

I asked the same question of my A&P/IA and he said absolutely to be
legal I'd need to install a current tso'd instrument; notwithstanding
there were no such requirements at that time (1948)
