Fork seals on a 2000 EC300 - help please UK

[BazzabikesMK]

Hi there - first post from me as a new member of the Gasser family !!

Will probably sound like a fool but I need fork (and dust) seals for my new purchase and I can't find out which variant of forks I have !!!
EC300 yr2000 with USD forks measuring 54mm at the top near the yoke, and the fork leg itself is 43mm diameter. Has the following numbers stamped on the fork cap 38.00 05500705B

Any clues ????
I'm in the UK and need to get the seals - would really appreciate any advice or pointers where best to source them (once I find out which ones to get !!!).

Thanks a lot - looking forward to getting it all sorted so I can go for a blast !!
