Long Roadholders. but for what?

Hi Roger, hmm i don't think so, the boss to which the brake stop is concentric is certainly part of the original forging. The nub of it is which model had a femaLe brake plate?

Hello again Jonathan,

So actually, the Manx Long Roadholder is a completely standard slider with a tapped hole and ground off lug and the standard slider has the "Bulge"?

Hi Steve,

This brake plate anchor is the type used for the Manx conical hub brake plate. look at a few different photos and you should be able to see the detail. I am not sure if these are Manx forks or not as the standard casting has the bulge to provide thisanchorage simply by drilling and tapping the hole to suit the male fitting and removing the road-going type anchorage on the lower part of the leg. If this has been done there may be witness marks left, particularly where the grooved slothad been machined. I don't think Norton used forgedlegs on the Manxlong Road-holders, unlike the featherbed Manx. Hope this helps. Regards, Richard.

Hi Richard, So are you saying there were separate castings for the road bikes and Manx versions? ie all long roadholders of this vintage have the bulge but Manx ones were made without the lower anchorage? It seems odd, you would think the factory would just drill a hole and grind of the anchorage... Attached is a close up...

Regards, Steve

My apologies Richard, I confounded Jonathans photo as a continuation of your informative response. My reply to his post is actually for you.

Re-reading yours, I think you are saying that all long roadholders have the bulge but Manx ones were made without the lower anchorage?
