Zetor 5545 4wd front hub seals?

hi, i've purchased a 5545 which is in quite good condition but i have a slight oil leaks from the front hubs where it pivots, i believe the axle i have is the early type, the tractor is 1968, i'm finding it quite hard to locate seals for this axle. there is a felt seal and then a rubber one.

can anyone lead me in the right direction? any info is most appriciated!

Someone on this board is making them aftermarket, or obtained them from a Roadless or County enthusiast.
These seals came from a GMC/REO 6x6 army truck. The allied forces left so many spare axles in Europe that there were enough to fill the demand for 4wd tractor axles for the entire 1950's decade. Selene of italy also used it.

thank you, does anyone here knows where i can get seals similar or who to contact?
