I recently ran into a web site for a company in England that does repairs on B & G instruments. I sent them my B&G masthead anenometer and they repaired it in good order and were quite timely. Their site is http://www.tinely.net/electonics or just sendd e-mail to elctronics@tinely.net. I could not find a suitable USA site. One USA place wanted a lot of money! Tinley Electronics was inexpesive comparatively.
