Catering Army Corps 1956

Hi, any idea as to what the marks are on the 2nd picture.
I would have thought a nice award like this would have be made with low level brass or metal. Thanks

 

Sterling, London, and if the last letter is a lower case d, assayed in 1959

Interesting that the competition was in 1956. Maybe there was unavoidable delay in producing the plaque?

 

So very clever - thanks

 

Possibly the “a” for 1956.

 

Not really convinced they look the same, but that is a good point.

 

56............imo

 

Army Catering Corps --- an elegant name.

 

The boys who could feed thousands using a stove made from an old oil drum. I'm seeing an a date letter too.

 

Some English sterling! Nice find! If my memory serves me correct, the markings indicate this would be from circa 1956? Please do correct me if I get any details wrong, still learning over here!
