Who Made This English Concertina?

[Daniel Hersh]

It's here on eBay. Distressed condition, but very elaborate fretwork. Is it a higher-end Lachenal? The case resembles a Lachenal case that I have. Here's a pic:

I would guess a relatively high level Lachenal such as the Excelsior or Inimitable but before the New Model

[Geoff Wooff]

The slotted strap adjustment would also suggest Lachenal .

[Stephen Chambers]

It's a high-end Lachenal of its day, that would have belonged to a serious player seeing that it's (unusually) a 56 key with extra fretwork, and it has fittings for a neck strap.

[Wolf Molkentin]

Might have been called "The Inimitable" (with ud adding "Extended Treble") those days, thus possibly not having the large scale reeds of The Excelsior and The Non-Pareil... but still belonging to the higher end series.
