At some point you will need to decide whether you're really going to use the RH or whether it's just going to be a collecter's item. Knowing your abilities, I think it may well rack up quite a few more miles.
In that case it will be necessary to resolve the gearing problem. Assuming the existing 4 speed block is not in good condition and has just the sprockets you want (unlikely) you will need to find something else. Four speed blocks didn't last very long (they were only about 15 pence less than a 5, so why bother?), and 1/8" must be rarer than 3/32". I believe the Simplex 4 speed 1/8 could be used with a 5 speed 3/32 (here I'm talking about the 'plunger' Tour de France type), which would give plenty of scope to find a block.
I don't know how your mech would deal with a 3 block, but I think I've got a new French threaded block (16, 18, 20) which you can have if it's any help.

Your find has caused me to find something which may be useful to me:
