Another vote here for W&H models. But also Kings Cross Models in York Way, the Victors shop on Pentonville Road, all three Harrow Model shops, Percy's in Uxbridge, the toy shop in Ruislip, the bike/model shops in Ruislip Manor and Eastcote, Railmail in Watford and Allmodels Engineering in Ruislip Manor. I am sure there are more I have forgotten. But all within a bike or tube ride from home in Ruislip ....... sigh !!
