I have one of the first batch of Speedbird IIIs and have had problems in the past with the screw down crown which Eddie has had repaired for me. It is now so old and the threads have worn smooth and it no longer screws down.

I know I need,
Crown (7mm ?)
stem (16 or 20mm?)
pendant tube (Double threaded external - maybe this one?) http://www.cousinsuk.com/product/dou...es?code=T45037

I've been searching cousins eBay etc and am no thoroughly confused. Can anyone recommend a source?

Can anyone tell me which sizes of the above are used on the SBIII and whether it is possible to buy a kit which has them all.

Any help would be much appreciated

Many Thanks
Rick
