Hello, I'm new here. I just received an older Leblanc Bb clarinet. It is exactly the same length as my Symphonie and L300. It has rings around ALL the holes in the upper section,and it has a shorter register key and a different mechanism for it. On the lower section there are 3 tone holes/pads on the right side (as you hold it) and the one on the left side. the serial# is a zero above 4869. o-4869. It does have what appears to be factory rings around all 3 of the tenon ends instead of just the barrel tenon. Any help is geartly appreciated.

A Leblanc with a Stubbins mechanism, perhaps?
There is a picture of the Stubbins mechanism here.
The Stubbins patent is available at Google Patents. Just key in the patent number: 2508550
There are a couple of pictures of a Leblanc with a similar-looking mechanism on this page. It looks a lot like the original Stubbins mechanism, but with the speaker vent displaced slightly--probably some kind of minor variation on the original Stubbins. It appears to operate on the same principle as best I can tell from the picture.

Hello, thanks for the information. I did check out the links providedI thought at first this clarinet may have the Stubbins mechanism, but the ones I've found do have the extra "throat" tone hole in the upper/lower joint with the pap on the top of the lower section. Mine does not! Maybe this is a variation in that I have 3 "large" tone holes on the same side below the "pinky" keys. Does anyone know the signifcance of the zero above the serial #? Thanks again. KB

TKS, mrn, for the Stubbins info and pat #, the ?who came first? [with the compromised register and Bb keying solutions] tho, goes to Leblanc via pat # 1,929,xxx [will supply if asked]. I understand that they did fight over it, since Leon's pat should have been cited in S's pat examination. It sounds to me like you [olddog] have another one of these [very few] Leblancs with this structure. We have one here in [my] River City OK, which the owner [and I] loaned to Debbi Reeves [NMMuseum, Vermillion S D] who wrote a definitive article on this subject in recent I C A Journals. I was intrigued also with the provision of TWO toneholes/pads for the lower F/C [ on "ours" and ? on yours], which is somewhat common for [at least] Selmer "type" bass cls, but almost never found on sop cls. Olddog !, can you post a pic of your horn, or comment on mrn's linked pics, please, you may have a "rare bird" here ! Don
Thanx, Mark, Don

You're absolutely right. I hadn't seen that Leon Leblanc patent before (patent no. 1,926,489--just looked it up), but that's the very mechanism that I said looked like a modified Stubbins mechanism. I guess it's really the other way around, isn't it? Interesting stuff!
