Hil - sorry, can't now find this item on ebay, however, sincere thanks for your help and suggestions.
Anne and Christine - is the hole leterally drilled? - or is the hole produced during the pressing?? Thanks - I am aware of the date guides during which pattern 269 was produced - but are we sure that this no. on the pressed metal base is a 'glass' no. - or is it a no. referring to metalwork?? The plating is of a matt 'brassy' looking colour, not the 'chrome' colour of the top of the pedestal. thanks for your time and effort - and as commented, I had not previously seen this type of base, so had assumed it was far less common. Think I will go with your date line, Christine, of just post second war. Paul S.
