This item is a genuine Renolds 'soft' link to fit a magneto chain. This type of rivetable link is always preferable to a 'split' type link and would have been fitted orignally.

This item is a Renolds 'split' link to fit a magneto chain. 

First and foremost i would say it is not recommended to fit a half link (or link and a half as it actually is), but I know that on some rare occasions you may have an unusual timing covers where the chain can either be too slack/tight with standard links. Therefore this item is for a Reynolds link and a half to fit Norton magneto chains
