Seasons Greetings and a Happy Christmas to all.
Originally posted this request in the 'singles section' but had no response. As the parts are technically "Slimline" cycle parts reposted here.
Now please see attachment, as a couple of pictures are worth a 1000 words. Plate one is self explanatory.
Plates two / three illustrate other fork parts parts; I stripped a set of Roadholder's from a 1961 Model 50 (Slimline) and the seal retainers had x 4 "C" / Pin spanner holes but were in bad shape. To get the bike on the road I "Borrowed" the seal retainers from my 1964 650 SS (obviously also Slimline) restoration project. I asso found out the hard way the fork lower fork castings are different......but I digress, so how about these fork seal retainers, any ideas?
Your learned knowledge& response would be appreciated
Rgds Steve & a Happy New Year!!

Attachment shows 3 of the, at least, 6 versions available for Featherbed Frames. Note the difference in the mudguard mounting points, especially the 1st pinch-bolt boot on the LHS of the group. Not on view are the Manx and post 64 wider yoke versions. As far as I can recall, seal holders came in two lengths and went from 4 peg holes down to 2 and then by 1967 to none. You had to use a leather strop to get them off and on.
One of the problems, about many of the Featherbed framed bikes, is how easy pre-1960 bits can be utilised on later models. I have often come across 650SS bikes sporting earlier forks, barrels and even Model 99 cylinder heads. I even came across a chap who had just purchased a 1965 Atlas which was wearing a Wideline Frame. He had no idea at all that his purchase was really a bitza.
G'day Phil,
Thank you for the picture and the 'Gen' on Roadholder forks; I suspect my 650-SS has later wider yokes, which would explain a lot! I have measured the Fork Seal Holder (FSH) parts now and see enclosed marked up PDF. I did not strip the 'strap tightening version's to measure thread length as I suspect this is the same (from memory).
Now back to the primarychain case in my original post (see plate one) is theinspection cover spring / post / retainer available asseparate part (s) or am I going to have to make something?
Regards Steve & Happy New Year!

Steve:
I can find no listing for the inspection cover (pn14837 or 06-7643) spring hold down device.
I suspect that it might be easier to find a primary chaincase that has been through a wreck and salvage the item off of it. The mounting post appears to be riveted on but you should be able to figure out a mounting for it.
Good luck hunting
Mike
