#2740 Balance Springs

A home owner from Indiana says:
I know the size of balance springs I need based on the stamped #2740.
I don't know what clips I need though.

Thanks for posting! Looks like you have an old Rollyson balance system. Check out our S371-28 as a possible replacement option. I would also recommend the 2740 option, of course.

Thanks Paul.

It must be Rollyson, I recall a neighbor of mine mentioning them awhile back. Are they now gone or bought out by another company? I don't find anything about them on the internet.

Also, do you think the difference in "angle" on the clips your are recommending will be an issue?
(see attached photos)

Thanks for your assistance

Hey, Chris. The angle isn't so different that it should be a concern. I would just make sure the size is the same.
