I for one do not commonly accept that. I respectfully disagree.

Personally, I think that's mis-information.
Just 'cause "somebody who plays an Alex and loves his Alex is
sure those B&S stencils are copies of Alexanders because he's thinks the
picture looks close" doesn't necessarily make it so.
While there are nuances that tuba players would notice, most rotor BBb tubas look the same. Miraphone 186 BBbs look like Alexanders from a distance. In all honesty, to most everyone
but tuba players, all tubas look the same.
IMHO, the B&S stencils play so much better than Alexanders, it's not even funny.
Poke poke poke ....
Everybody knows that Alexanders are Cerveny copies anyway.
