Roto BB and R531, so it can only be an AA frame.
I don't think there are AA-Specials with ROTO bracket shells, but I can be wrong.
Yes, the AA-Special came with Roto too Dc. I have one here in greyish/silver with blue panel and HT. If I recall correctly my old Stayer has a Roto shell too. Probably also for early pistas?
