God - this has stirred some memories.
Two floors - ground level and basement. The gorund floor sold Prams and Bikes but I remember them having a huge railway set which could be rigged in the garden and rode on - cost hundreds even back in the 60's - but we lads all dreamt about it.
Downstairs - a kid's heaven - with 2/6 pocket money Saturday Mornings were spent as long as Mum could stand it - if Dad took mewe stayed a lot longer 'cus he got tied up with the Models etc.
There used to be a ride on helicopter which for 6d - took you up to the ceiling (or so it seemed) - I also remeber the Airfix Models which had been built and hung from the ceiling - the detail was incredible - I once saw the guy who made them - he was in a wheelchair and was painting a model.
They also had a sister branch in Fitzalan Square called Wison Gumpits or something - but they mainly sold Prams and Bikes I think
