Help Needed with Odd Configuration for Polerouter cal. 215

I bought this cal. 215 Patent Pending Polerouter last month from a Private Seller here. I looked at the reference table on universalgenevepolerouter.com and the closest reference I came up with is the 20357 but that one has "microrotor" on the dial. My watch movement dial does not say microrotor on it though.

I've asked asked some well known people with expertise on Polerouter configurations and they are not aware of this calibre with the dial I have. I was asked for the serial number but unfortunately there isn't one visible, either on the outer caseback or between the lugs.

Is anyone here familiar with my configuration?

Any guesses as to what’s going on? I think it’s the wrong dial for this movement.

I'm not super familiar with this level of detail on polerouters, I think you need @CafeRacer or @Mazoue

Thank you, they are two of the people I contacted. They were as helpful as they could be given that I don't know what the serial number is.
