Does this german Electrola hava a reentrant horn?

[muzafan]

I was wondering if Electrola was German HMV were there reentrant horn models? This offer may have one, but I have not enough experience to say for sure. https://m.olx.pl/oferta/gramofon-patefo ... n=3&page=1

Yes Electrola was owned by HMV and this is the Electrola equivalent of an HMV 157 "reentrant" gramophone as described in the catalogue , however it doesn;t in fact have a reentrant horn but a smaller bifurcated horn

To be fair, the 157 was not called 're-entrant' in HMV catalogues originally -- although it could have been. The term was the company's own, so they could use it as they wished, and the 157 horn does 're-enter' (i.e. the sections re-unite at the mouth). In practice, they carefully excluded it from the 're-entrant' category until sometime in the 30s, when the emphasis was on radiograms and it didn't seem to matter any more. Could have been an unintentional error, even then!

Most Electrolas were identical to HMVs, and the range did include re-entrant models.

I'll agree that while the Gramophone Co. didn't coin the term "Re-Entrant," they made it their own. The Victor Talking Machine Co. actually used "Re-entrant" to describe the tone chamber in their Orthophonic Victrola manuals prior to the introduction of the Gramophone Co.'s line:

The Gramophone Co. exploited the term "Re-entrant" as part of their campaign to market the gramophones, most likely because Victor kept the "Orthophonic" brand name when they sold the Gramophone Co. the production/design rights. I've also seen some early ads promoting the line of HMV gramophones in which the term "matched impedance" is used to describe the models--the soundbox is matched to the tonearm, the tonearm is matched to the horn, etc..

It's also interesting to note that a metal two-chamber bifurcated horn design was used in the Victor Credenza's replacement, the VV-8-35.
