I'm still confused about the foam question. I have yet to confirm foam or felt in my A-102. Serial 2136X. I always thought this was before they went to foam.
*Update*
I verified the age of my organ by serial number, speaker date code, and reverb tank date code. Early 1963: before the felt to foam change. I couldn't figure out why my instrument had foam. I finally figured out that at some point the manuals had been changed. Now I know to not only go by date but also check the manuals themselves for rivets.,
Cheers
