Ahhh! You have a nice oulde one.
Back to the 1880's or '90's latest.
Chain is probably 1"X1/4" wide, maybe 5/16 or3/8 widest, would have to
measure.
It's possible it was machined out of one piece of stock, but if you do some
fine cleaning you may find a seam and when built up could be removed. You
could make jigs to hold it without damaging either element but that's a lot
of work.
If you look close you will see the holes are countersunk for opposite spoke
pull direction for straight head pull.
The best place to find info is from "The Wheelmen"group who are super
collectors and nice guys and gals restorers of bikes about to WW1 and older
the better kinda folks.
Several of our group are members also.
