Help with a seat clamp

[coasterbrakejunkie1969]

I have seen this type clamp before but cannot find any info or images of it. Someone was talking about them not too long ago. I'm guessing '50s? Would love to know what bikes and it's age. Thanks

Is that one for 1" tubing or the larger CroMo tubing? I've seen a couple of the prewar Superiors with those clamps, first models to have the removable seat post clamps. But I can't find you a picture of one. I believe @rennfaron has some in his files.

I’ve also seen that Clamp on some early postwar lightweights, and I think they were all the large frame models. The top tubes are all the way to the top of the head tube also. Been trying to find a picture of one but haven’t had any luck yet.

Late 40s (I never got the actual year on this one...I think it was a 1949 though...)
I swear I have seen it on something else too, but can't remember ATM.

I have one that came on a 1950ish superior.

I have one of those that came with a box of other bike junk.

I just picked one of these up Thursday and thought the same thing/question.
Has to be a lightweight thing.
Yeah, decals on the green bike make me think 49/50, first one I've seen the clamp on.

That green one is a 49/50. Was originally in Massachusetts and bought by another member here. We PM'd for awhile about it because I also ended up with a green post-war Superior. Mine came from a collector in California. The bikes were mostly the same, but one of the differences was the seat clamp - the one from Massachusetts had a tapered clamp as shown here and the one from California had a standard New World style clamp. Neither one looked to have been a replacement and both matched up with marks on the frame tube. The neon green 1949 ladies' model Superior that sold recently on here also had a New World style clamp. There is a red color 1949 Superior that has been on eBay for awhile that also uses a New World clamp. There was a sky blue colored Superior that sold on eBay awhile back, and I think that one had a tapered clamp if I remember correctly. 1949 catalog image shows a standard clamp. I would guess the post-war Superior could come with either the tapered clamp or the New World style.

Has anyone ever seen a post-war Superior with its supposedly original Brooks B73 triple spring saddle on it? The image above shows a B73 but I've never seen one on a post-war Superior. I've seen several with old horsehair and fabrikoid mattress saddles, but never a B73 saddle.
