Interesting. Perhaps early stencil heaven? These French common law brands are difficult to trace to makers and even if you find the maker at one time, 5 years later another maker is using the same brand. Usually most of the prime suspects are desirable makers. Any peculiar marks? You might want to compare it to my CLP Couesnon, which might be a little later.

The key work is quite similar to an A. Hindley clarinet that I featured on an earlier thread. this was a common type in England at the time but the name given to it escapes me. The distinguishing element is the way A and G# are laid out on the upper.

The socket rings are also similarly flat.

Bakelite was in common use after about 1915. It’s fairly easy to spot Bakelite side by side with hard rubber. While it can be scratched, it is far more resistant to light scratching than rubber and has a very crystalline sound when tapped with a hard substance and the engravings tend to have very sharp, precise lines.
 
The best looking Bakelite entire clarinets I have seen were by H. Bettoney. Many others feature Bakelite bells and barrels or mouthpieces, but usually not joints.

Another joint pair and bell with the dual marking just sold on eBay for a very nice price. 

So I will keep my eyes pealed for a bell and barrel to match. My investment in the joint pair was a tiny fraction of this recent sale price. The pair I have is the same HP Bb Albert type as the recent sale.

As I put together parts, the history of makers and brands also comes together. 

The abused M.R. Verney modele Breveté that arrived with an accessory tunable Mercado USA barrel now has a barrel marked E. Bercioux, Paris, Breveté, thanks to an eBay seller. It is the same length and bore as the other Verney barrel, larger outer dimensions more like earlier JTL Legion D’honneur models.

It’s probably as close as I can get to original unless I luck into one like it marked Verney. E. Bercioux was the successor to Martin Thibouville and patented the mechanism on the JTL built Verney modele Breveté. As the Bercioux barrel is also marked “Breveté”, it is apparent that E. Bercioux marked clarinets were also built with the mechanism and this barrel came from one of those.

The Mercado tunable barrel might have been an “original” accessory provided by Wurlitzer, USA, but the plain wood Bercioux is a far better match. Even the font styles match.

Another thought;- look for marks under the keys like I found on the other early Lafayette. These could be clues to a maker.

I think the first MBIC Pedler I took a chance on came from a seller who had it and a very nice D. Noblet available at the same time, both good prices. I also was immediately impressed and felt that these were under valued considering the quality construction and materials. I was not disappointed by the sound or playability either. There seem to be quite a good number of these still in restorable condition, which makes them great candidates.

Gorgeous!

The barrel appears to be from a later Couesnon Lafayette model, after Couesnon located to Lafayette Street. The rest is similar to a pair of circa 1900 Lafayette marked Albert types I am working on, but yours has more rings.

While I am relatively certain these are from a La Couture maker, I am quite certain that these 1900 Lafayette marked clarinets are not Couesnon.

It would be interesting to see one side by side with a JTL with similar features. Most of the French clarinets built at any given time look quite similar.
