Kriegsmarine Silver Cutlery Rest

we understand this tool to have been used in the Officers' Mess for formal meals to enable cutlery to be rested between courses to prevent soiling of the table cloth. We have, however, been unable to positively identify, so if any of our Kriegsmarine collectors can give us confirmation, it would be appreciated. The item is stamped on the base with a fine Waffen Ampt and a large M below. It is also marked with 90 which we believe confirms the grade of silver used and beside this is a maker's mark. In excellent original condition. Price indicated is for the pair. We would be happy to sell a single stand at £55.00 Measures 4.75" (11 cm)
