1897 Orient Model B Racer Project

[locomotion]

My 1897 Orient model B but a Ladies bike also has that screw. On the parts chart that @Jesse McCauley shared, it seems to be parts 1134 and 1135.
I never took apart the seat post but my guess was that is was there to hold and keep the seat post and clamp from spinning.
guess, I will have to take it all apart this week and study it a little more.

the seat clamp set-up seems different from the mens and ladies bikes

***Update*** I wonder if I am missing the large locking nut now that I see the parts chart ..... seems like all the boys have a locking nut

Yep that is just the sort of 'tabbed' bit I thought may have been there once, my example also has a tiny hole there in the seat tube exposing the post coupling in the same fashion.
Suppose I need to try and fabricate or find something emulating what you have there Max.
If you do pull that screw and if that little 'tabbed' bit also comes off easily I would be very curious to see a photo of that part independently.
Many thanks!

As promised, I took apart the seat post assembly on my bike and the little clip (held by the screw) is there to keep the seat post tightening sleeve from spinning or from entering the seat tube while inserting the seat post.
A simple longer screw could have done the job just fine .... But 1890's engineering at it's finest.

I am also missing the top large nut on mine, but luckily a CCM fork top nut works perfectly as a replacement ( same tread) what are the chances of that?

Here are the original pedal from both my Orients. Men and ladies size.
Look a lot like the pedals you have Jesse.
You have all the right parts

An updated rebuild with some Fairbanks racing wheels and US racing tires as well as a set of Leader bars and stem.

Sooooo what year do y’all think Orient stopped using the button with info on it that is behind the set post?
