Thanks Dan. The picture looks like an original so is really helpful. Itlooks as though there is a slight gap between each coil which agrees with the written description I have on some period literature. Most of the pictures I have are of 'restored' bikes which might explain the variations in number of coils and they all have closed up coils. Thanks again - Steve

Hi Guys
Hope someone can help with some info on spring dimensions for a 1924 Ace please.
My (almost complete kit) Ace is missing both springs in the front fork. I need the diameter of the wire, the outside diameter of the coils, the free length of the coil and the number of turns for each of the two springs. Then I can get some made. Please don't take your forks apart for this - I'm hoping someone will have a set of forks already dismantled!
The other springs I need are the seat springs. Now, you would think this would be easier but counting the number of coils on pictures of Aces found on the internet and in the books give numbers varying from eight to sixteen.... Just wondering what the originals had? My Ace is 1924 so I think I need the single spring each side rather than the later double spring arrangement but please correct me if I'm wrong!
Thanks in advance for any help you can give
Best regards - Steve
