No need to suspect, the T Control unit is a T32 Flash with the head
swapped for a socket, or you could say that the other way around.
Shared parts are cheaper.
I have in the past fixed a T Control unit buy removing the broken
flash head from a T32 and putting the socket head in.
The 28 comes from having a smaller head, lower emission tube,
and so it also doesnt strain the charging circuit, and remember
it has two smaller heads.
And there is something else at the edge of my memory I cant
quite remember about it.
Cheers
