Is it me or has no one mentioned Garth Model Co on Whitchurch Road?
Lendons as I lived in Llanishen was my model shop, Mr James or the James in James and Lendon ran it and was always helpful and would happily show me what ever I wanted to see that he had in stock.
Dispute the fact my pocket money was only 50p!
James and Lendon was a bicycle (James) and model shop (Lendon), something happened to Mr Lendon and Mr James took over the modeling side or so the story goes.
