I've cleaned and refurbed hundreds of pipes over the past few decades I have been in this hobby, so new guys just hush up please, no disrespect but your thoughts and guesses will not be touching the pipe in question

A few years back at a junk store I picked up a 1920's one dot Sasieni. Now this particular one dot Sasieni has the patent number on the stem identifying it as one of the very few that were shipped to the US at that time as opposed to a diff pat number for the European version.
I gave it a refresh at the time under the philosophy of "do no harm" so I removed nothing that was there but really just cleaned it up nicely. I have since smoked the bejeezus out of it (for a few years now).
I've got a new chuck and jaws on order (sadly still using the stock ones) as well as some nice briar blocks on order that have apparently been lost in the mail - eventually my stuff will show up though and I would like to reproduce this pipe, refurb the original, and maybe sell as a boxed set (my new one and the original)
So questions please:
Would any of you have a cite to the patent numbers so I could reference it and validate this as a US one dot? I had the link at the time I found the pipe and researched it but my Google-Fu is failing...
The stem at patent numbers is oxidized- I will not be able to buff and keep the remaining, still eligible, patent numbers. I know lots of ways to do this without buffing but they all require elbow grease amounting to buffing and I will again lose the numbers. Anyone have any thoughts on refurbing this pipe and keeping the patent numbers without having an oxidized background at that locale?
Maybe when I make the new one I should call it the retirement of the old one? Maybe I should just send it to George to refurb? Or am I off my rocker again and this pipe is not as rare as my research showed my first go around?
Thanks,
Bill
