Can anyone I.D. these bits please?

[Tommo]

The bits in the attached photos were saved from a scrap bin and when I got them they were hanging all together on a wire.
I don't know if they all belong to one assembly or if they have come from several different ones.
Once cleaned up they seem in pretty good condition but I don't have a clue as to what they fit.
Any ideas, anyone.

Tommo: I believe the parts may be for an early Indian roller drive. Around 1908, Indian used a roller drive from the engine to the countershaft because the engine ran backwards. Tom Wilcock, AMCA 381

Tom,
Thanks for that as I was beginning to think that maybe I should hae left them in the bin.
Are they of any use to anyone out there?

Tommo: I checked with a friend who has a 1908 Indian and he says these parts are not Indian. Tom
