I would start with very accurate measurements of the diameter and thickness in inches and mm. Oil seals are standard items almost always. Don't know what companies are there or will ship there, but here McMaster-Carr, Grainger, and many others sell seals by size. Check this: https://gacoseals.co.uk/

Metric seals usually have the size on the face, three separate numbers that describe the seal. Seals measured by inches go by part numbers which can usually be decoded. This is how I always have seen it done.

EDIT:
but then there is this

ie

30-4716

Seal, 25x47/55.5x16

Gaco SMIM designs were normally numbered by size in mm.
SMIM 304710 ( 30mm shaft, 47mm OD x 10 wide/thick) would be a standard size. 16mm wide would be an oddball size.
single lip, rubber covered, metal insert seal.
I'd be interested to know this seal's actual dimensions.
