"Expression" Sound Box? (copy of Exhibition)

[Jwb88]

I saw a small upright gramophone for sale here locally (California) and while having no obvious branding anywhere on the cabinet, I did find the sound box somewhat funny. Obviously a copy of the Exhibition. I have seen "Exportation" ones before, but never this, "Expression." Made in Switzerland, yet also the "best American sound box"?
Just curious if this commonly found and if so, on what machines?

I have also seen "Exposition"

I think there's also an "Expedition". There were many European copies on the Exhibition soundbox but the best ones to collect have similar sounding names.

I think many of these are fairly generic and were sold individually as upgrades.

I also have one "Exposition", very similar to the Exhibition but with three back screws instead of two attaching the rubber ring. The rest looks identical.

Likely they meant "Best American-patternsound box."

From the 1911/12 Beka catalogue, here is the "Exposition" :

I have one of these Expression sound boxes that was on a Victor III I bought years ago.

On a related issue- I have a Decca portable from the early 20's - the soundbox is only superficially like the Exhibition, BUT - the exhibition rubber back fits it perfectly.
