On the reprint of the “Roedean” frames apart from the two 1 1/2″ radiuses, no dimensions of profile radiuses have been shown. Are these going to be published at a later date.
Hi. This might help if you have copies off ME there was a design by N Evans for schools class Stowe. I know it was in 5 inch but the frame drawings had all the radi on them. Fancied myself but chickened out as first loco one day . Hope it helps . Regards Gary
