In the late 1980's (?) there were many pairs of 7x50 REL binoculars sold at Crown Assets sales in the Toronto area. Amongst them I saw a few of the BOF 7x50 binoculars with the adjustable filters. I still have one pair: there are no broad arrows impressed into the leatherette as shown on Mike's binoculars but the markings are generally the same except that the right side is embossed C.G.B. 57 G.A.
R.E.L. 7 x50
7212-C
There are no other markings such as date etc. The 2 screw heads on eiher side of each filter selection knob are painted with red paint, I assume to indicate if they have been tampered with if the paint has been disturbed.
