Our Ruby ran on 4-50s for many years because, as you say, 4-00s were unavailable. They are indeed far too big! More recently I've been unimpressed with the Longstones which are on it at the moment and I'm wondering whether to try one of the various makes of 4-25s next time. Excelsior, TT Classic Roadmaster amongst them.
