Told you there was another question

[Melvyn Hiscock]

'Can anyone confirm if the BG4B2B and BG417-S are compatible? I have
heard from somewhere (can't remember where) that the BG4B2B can be
used on the 145 Warner and because they are so cheap that seems like
a good idea! However, I am not about to try it to see, I wondered if
anyone knew. I also understand they are not approved over there but
we can use them here in the UK so any ideas?

Thanks chaps,
