Lamp Lense Seals

Help!

Does Anyone know where you can buy the small rubber washers that seal the screws inside the front and rear lamp lenses. I bought some off EBay a little while back off Margaret (Atkinson?). Bloody things were far too big - more like tap washers - cheers Maggie - nice one. The correct washers are around 7mm OD, 3mm ID and 1.5mm thick.

I did buy some of a perfect fit around 6 years ago, but I forget from whom I obtained them (not Wadhams/Walker or Weekley). I did enquire with a local manufacturer who told me their minimum run was 1000 washers at 4p each, despite them boasting on their web about low minimum numbers of 100 - bunch of shagnasties!

Can anyone advise?

Thanks

Paul
