Ol Duke,
Did not see the forum where the Madsen is located to post this question.
The Danes called it model 1947, and the Colombians called it model 1958,
so what is the significance of "M. G/A." on the receiver?
Thanks,
Richard
Are you still collecting serial numbers for the Madsen?
If so, mine is 0711-58, original stock, no bayonet.
