Thanks for those replies. I have gone back to the diagrams on the EPC and looked at the springs (A123 262 0193 and A123 262 0293) associated with the synchros. They are circular in shape. The spring I have found strikes me as possibly being much the same shape it originally was. For it to have been distorted to this shape (from a circle) within the transmission would surprise me. You see, it is very stiff and springy and I believe any attempt to bend it significantly from its original shape would cause it to break (as one end of it already has - see smaller section in photos). I also notice that its shape is very symmetrical and all of it except the ends is perfectly flat in one plane. Could those synchro spring rings really end up so well formed into this shape? Its present shape appears intentional.

With regard to the operation of the synchros, they seem faultless (although I am in the habit of double de-clutching down shifts from spending my early driving years in a car with lazy synchros). The only gear that is occasionally baulky is reverse, requiring the clutch to be engaged briefly again before reverse can be selected. I can't remember if reverse in this transmission has synchro, I know some do now.

Getting back to the broken spring, the closest match I could find on the EPC was either part of the shifting fork assembly A124 260 0730 or the spring A124 993 0325. Even these are not the same shape in the drawing as the item I have recovered from the magnet in my transmission. Whilst the EPC diagrams are only approximate, I usually find the basic shape of parts appear correctly.

Again, thanks for the replies.
