Lewis will take some photos and post.
Mine is a R&P also unlike the newer models my adapters are pushfit with thumbscrew only no thread on the inside or outside.
I would like a non snoot style like these ones

One is zero profile fits within , the other has a lip and threaded for borg m57 fittings. But both are straight tubes. With snoot design you add distance due to the gradient. I would like a fit within as this adds no length and would then allow for a diagonal. I prefer diagonal for visual as it's easier to use with refractors. Looking straight through can be straining on the neck
