The idea of using cheap, available 45 degree (or 90 degree) Hasseblad or Kiev prisms on TLRs has been around for a long time. Baier Photo used to make an adapter (or still does?) for later Rolleiflexes that already had the native capability of interchangeable hoods. Other hobbyists have rigged up homemade 3-D printed adapters (with tape to secure them, not ideal) to work on cameras like Yashica 124s. I really, really would like to do this, as these external finders make using TLRs way easier for me. Is anyone out there making adapters for non-late-model Rolleis? Or could do so? I would be really interested. Here is a Kiev non-metered prism sitting on top of my TLR.
