MicroMetal Motor Part Number or Details?

I recently received two MicroMetal motors and attempted to look up the detailed specifications. Unfortunately none of the part numbers I have available seem to match the numbers given in the specification document.
Both motors are marked with TT 09190, and one has 0037 210310 while the other has 0037 210288 as a second identifier.
The motors are not encoder compatible, and are the 50:1 gear ratio variants.
The specification document I found is at https://www.pololu.com/file/0J1487/pololu-micro-metal-gearmotors-rev-6-1.pdf which I found from a link on the page Pololu - Micro Metal Gearmotors
Can someone advise what the full specifications are and/or where to find them.
Thanks

Hello.

Those markings do not appear to match the ones on our gearmotors, so they probably did not come from us. The form factor of our Micro Metal Gearmotors is fairly common, and unfortunately, I do not have any recommendations where your motors might have come from.
