front wheel bearings xc 500 1985??

i have taken my front wheel bearings out of my husky 1985 xc500 they are really corroded and my mail order bearing supplier has asked me for the 'bearing number' printed on the bearing but as it is so bad it is not there does anybody know what he is on about or what it would be?best regards Dave.

It is a 15 mm bore for sure you could measure the outside diameter and thickness specify two rubber seals and the guy should be able to look it up it is probably 6302 but I might have some numbers transposed. Bearings from reputable sources have a number, a brand, and a country of manufacture. You might be suprised how many made in england bearings there are in your bike.
