Smiffy. Ah, Commander Chuff- a name from the past. I would have loved to have seen that layout- I still think it was Dover but you seem certain it was Folkestone. I tried to go on the old KHF to see the list of members, in case there was a way of contacting him, but no. My nephew had a large layout of Trix 3 rail & I bought him a boxed set of ack-ack gun, searchlight, etc. waggons. Probably worth a fortune now for prices are reflected by new & as you say, they are horrendous. These all came from a little shop in Liverpool in the late 70's, that bought & sold everything model railways. Was there a shop like that in the Medway Towns?
