I can see using in line filter in gravity fed systems , have fitted a glass bowl type ad shown above in my Chummy. I don’t know if the banjo filters are available but I make my own, can supply a few at a fiver a pop.! They were 6d each in 1937 which I think you will find equates to somewhere near a fiver today.
I am always interested in any information about Rosengart details or current owners.
