Cb500 Spedo wheel drive oil seals part numbers?

[McCabe-Thiele (Ted)]

I can't seem to find  part numbers for the two oil seals in the spedo drive unit.

The larger seal is NOK marked  AE 1967E with no size  the smaller seal at the drive output end is marked Ars 13  50 or SO  4,8  & 4.
Does anyone know part numbers & a source please?

Update: I think the larger seal might be the same as for my 400 - OS 34 x 48 x 7 R32 double lipped seal - not expensive.

They are just a dust seal and a grease seal Ted. If they are not totally destroyed, just use the old ones.

The small one is in very poor condition I did source one for my 400 I think it might have been this one below not sure.
I'm concerned about keeping water out with the unit being where it is.
I can't find my e-bay paperwork for the small seal except it was £2.87 on the 9th December 2021.

My measurements of the small seal are 15 o/d 4.something i/d,  thickness 4 mm
