Picked this up, is it a No5 or a No23?

[Reenactor1939]

Got this the other day and I think its a No23 but wanted to be sure as I start trying to find the missing parts....which won't be easy considering I'm in the US. Mills in general seem to be really hard to get here in any condition.

The Military Man (Worthing, UK) sell first class reproductions of the missing bits at very reasonable prices but I don’t know if they ship overseas. It might be worth asking them
