Hi Michael,

FSD = Frederick Samuel Dinnis, born 1st October 1903, died 18th July 1989.

The address in Ward Avenue Cowes was a very nice detached house though bombed out in WW2. That address will be be very well known to older model engineers of the loco fraternity.

Cheers,

Julian

Thanks for your contributions to the debate gentlemen, its helped clear things in my mind, and added to my understandings of the issues.

The use of brass as against the longer lasting bronze for the burdon tube reminds me of how we were priced out of the market by an inferior product:-

Back in the dark old days when I worked for a living and we had a manufacturing industry, one of the products our company made was bellows for the chemical industry we made quite a few different types, from brass,bronze stainless steel etc. What made our's special was how we made them we formed the ridges using rubber, the ends of the tube was held free so that that they formed with a uniform wall thickness, our competitors made them using hydrolic with the end clamped so the material thinned, so they didn't last as long, but everything comes at a prise ours cost a lot more but we're used where long trouble free use was paramount, but in the end we were even priced out of this market.

Thanks

Again

Stew
