The RichMan is indeed coming from the same factory as the AGA line of RBA's, sharing the same packaging and spare parts bag (just RichMan branded)..as well as a similar design, but that is where the similarities end. The RichMan is much higher grade steel, and is made with much higher quality components. Even the post insulators are of better design and quality.
This is standard in a lot of manufacturing industries, lets say for example pens or my favorite other hobby, watches. The factory has a design, but for a price and minimum order, will produce you a run of the item built to your specifications, all for a price.
Richard made all the right changes to the AGA design. These RBA's are fantastic. The heft of them is amazing. Really guys, if you like Gennies, get at least one of these. They are well worth it.
