Hi Lance, just looking for a source of parts (in particular the diaphragm)
Not needing anything yet, and certainly not asking you for your spares.
There is a lot of commonality between these carbs. I assume your ones are ferret ones. the early british carrier carbs are from memory RZNIP or RZINP model
They are a governed single barrel with an adapter to the V8 Manifold. I also have a NOS two barrel one at home, that I think is a Loyd carrier carb.
An old guy advised me not to use the original Solex, on a carrier, if I want a decent turn of power.

Lynn,
Yes, I really need 40 RZINEO, the ones that I have found are 35-40 RZ-42 (which work for HSC and the HAC, but have to slightly modify the linkage or use an adapter plate to turn it)

Dirk L (lwdparts.com) has the ones that you are looking for for sale complete, I will look at my other sources for some rebuild/gasket kits for you:
