British Navy CF41's and a CF42 ( with rubber head rest) by the Barr and Stroud of Anniesland , Glasgow.
7x50 with in built filter system which offers 4 differnt filters from yellow down to a dark green , very effective in reducing glare from the sun.
Visible on two of the three sets brass screwhead linked by chains, - decicator ports to allow the sets to be purged with nitrogen to remove mositure.
Optics are uncoated , prism housings are off ebonite / bakalite, individual focusing.
The CF42 in the background has a graticule , other two CF41's do not.
Set on the right has extending anti-spray hoods .
Not deemed to be very collectible in contrast with German navy sets , they are generally less refined and more "workman like".
Prism glass would not be as good quality as those found in German glasses which is relfected in the preformance.
Most if not all Barr and Strouds do suffer from failure in the balsam cement which holds the prisms together ( Porro II construction).
Having said that they are an important piece of our naval heritage.
Easily obtained when cleaned and restored they are quite good and are worth having .
sadly Barr and Stroud as a company disappeared in the 1970's being bought over by Pinkertons, the workshops are gone , in its place stands a Supermarket ( Asada ,I recall ).
Good price for a restored set , about £90 .
next time you watch " A Bridge too Far" , the assult by SS troops on Arnhem Bridge , why is a Knights Cross holder wearing / using a set of British Navy binoculars by Barr and Stroud.
