Exactly. We
call the first 2 'B7G' and 'B9A' over here, BTW.
We call the first two 'miniature' and 'noval'.
The 'Noval' is sometimes used over here, along with magnoval for the B9D
base (as used on the PL504, etc).
'Miniature' is used for any small valve base, including the B7G, B9A and
B8A (Rimlock base, as on the EZ40, etc).
