John,
Thank you again for your reply.
I put together a list of possible inclusion to the B-57B avionic fits and would like to ask for your informative opinion regarding the installation of these electronics in the 1954-1959 timeframe for tactical bomber units only.
GOOGLE and various web pages dealing with B-57B avionics, confirm that all the items below did indeed fall into the 1954-1959 time period. But were any or all fitted in the "B" model? If you care to comment on my post, please add or delete any items which, in your opinion are, or are not, relevant.
