sincere thanks Pamela - your information is very much appreciated and of course very helpful. The size matches the figures I had from my own STS bowl. However, can I be 'Mr. Picky' (troublesome) with a last question. I quote Bernard earlier in the thread, where he said......."it's also Walther plinth No. 3, listed in their 1937 catalogue in three sizes, made to support their Berlin bowl".........I assume only one size was for the Berlin, the other two plinths, although similar in design were for completely unrelated items. thanks. Paul S.
