Nice project this! Reminds me of my grandma’s 1936 Merlin, which I must get round to putting back together. Currently it’s on the wall..
Resilions also could also be attached with a bolt through the forks/seat stays, as they are on my tandem. I agree they’re hard to set up and on a slightly wonky wheel as my rear tandem wheel is, they’re not very effective. Luckily I also have a hub brake on that wheel. The front one is great tho. I managed to find some old blocks to use, but modern removable v brake blocks also fit. However they’re very thin and will wear out in no time.
