Updated; Overland reed type Tillotson. Might be going on my T at some point.

I think I have ID'ed the fitment and Model number. Anyone run one of these on an Overland or other?
I just got what I am pretty sure is a Tillotson carb. The cover is missing over the bowl and every other markings are just casting numbers. It has a spring steel venturi that opens as more air goes thru and is wedge shaped. The opening is about 1" at the throttle plate and center to center on the mounting holes is 2-3/8. This might replace the OS-1 on my Chevrolet overhead when I put it back on. The OS-1 is the in the ball park for the T engine size but is more carb then I need or want. The economizer does not ever come in to action at the speeds I drive so have been looking for a more simple carb.
Any ideas what this one may have come off, model number or if you have used one, how was it?

I once had a similar design down draft version of this carb that had 1915 patent date on it. Turns out it belonged on a ‘20ish track dozer of some sort. Found this out from an avid tractor collector, who also reported that that the reed style venturi carbs were great at idling... and nothing more!

Here’s an old thread bout the downdraft version. You may reach out to the OP about his experience with the reed venturi carbs

Once I saw the word reed it helped my search;

Thanks Kevin, I will try later. He was last on line in March of last year. Looks to be a 1920 or so Overland carburetor.
