Cast iron washers what where they called?

[Restoration man]

Hello,
I bought a load of old cast iron radiators from a fire station that was being refitted. They are the wide single column type (profile is like a propeller blade, ish!)
One of them had a washer left on it because it was painted over. I've cleaned it on a wire wheel see pic. It is a cast convex washer that is obviously from the original wall stay but I only got the one!

Any ideas if these where made by the radiator company's or if they were in general circulation for some other purpose and were simply used as the wall stay washers because they worked?

Did they have a special name?

I've refashioned one from a flat steel bar but it takes a while and I need quite a few. I'm putting together my own wall stays as its easy with threaded bar and plumbing back plates and I don't fancy being shafted for £25 a pop for the ones off the poncy new old radiator sites.

Any shaped washers I could use like this?

Only other alternative I've come up with is wrought iron convex bar which Id have to cut to length and drill holes in.

Cheers
