Talk:First World War glass–rubber exchange

Lead - who proposed this deal?
The lead says "An exchange of rubber for optical glass was proposed by Britain and Germany during the First World War.". Yet the article body seems to say it was only the British that made the proposal. (Hohum @ ) 13:15, 11 November 2018 (UTC)

"US binoculars unsatisfactory": Bausch and Lomb or Crown Optical ?
Are we sure "an offer of binoculars from Bausch & Lomb was rejected due to an unsatisfactory design" ? I have found a reliable source saying it was 'Unsatisfactory binoculars supplied by Crown Optical Company of America'.

Of course, both manufacturers may have been rejected, but many Bausch & Lomb binoculars were used in WW1, marked as 'S.1', the highest standard.
