Just an update: this is what I ended up with doing for my shaving horse re-build, there is hardly anything left of the original.
you can see all that I re-used is the head and lever. it’s also a little bit longer than the old one… we’ll see if that’s useful or if it’ll need to be shortened. Nearly 30 years on the old one isn’t exactly a short span for a wooden tool that gets left outside. If this one lasts as long I’ll never need another.
