I took these off to the nice lady in a nearby village (suburb really) for the necessary (vital really) alterations. 
Like Silvermans' (as recommended by Uncle Ian), these are Made In India, like plenty of Madras shirts (and where more appropriate?).  One hundred per cent cotton, almost creamy in colour but not plain-fronted.  Some would rule them out on that basis alone.  But (in my imagination perhaps) they look not unlike those Mr.Allen is sporting on our Gibson's IG page, CN2P.  I'll try them out with a similar shirt and see if nubile young women come running.
Seriously, for the money, they're all right - better, in some ways, than the USA-made L.L.Bean I bought on Ebay Com last year.
