Service manuals can be found here, they have the tube part #:

Double check the different region tubes too, USA usually uses 20F1U or 20E1U (not 20E1E which is EU version, right?).

According to the seller, this tube is used in:

BVM-20F1J
BVM-20F
BVM-20F1E
BVM-20G1
BVM-20G1E

According to savon-pat, I would need the EU of the M49LCB22X for the BVM-20E1E.
