Help needed on unknown medal

[History_dealer21]

I have recently obtained a medal which I have been unable to identify and would greatly appreciate any help on it.

[922F]

Copy British DSO.  If this is soft metal or plastic & about 25 mm  or 1 inch wide, it likely dates from the mid-1950's.  A series of perhaps 20 similar manufacture awards were sold individually with a 3 fold cardboard display mounting.   The idea seems to have been 'collect 'em all!'   The ribbon & pin on your example, however, differ from that generally seen on such pieces.

Another edition of these same items in plastic painted in colors approximating actual enamel work exists.  Those had a much coarser woven ribbon, often in colors similar to the originals.
