wish l could attach a pic, think its old, looks it. has a red background with raised letters. It`s a 28 inch arc and is 4 inches wide. Cant find any info about it, any help plz?

MALTA.G.C could stand for Malta, Gozo & Comino or, more likely, Malta George Cross

Malta was awarded the George Cross after the bravery of the people of Malta during the Siege of Malta in World War I l by King George V l in 1942

If the latter, then might l suggest that u offer ur plaque to a war museum?

There were several locomotives named ''Malta most were later renamed to ''MALTA G.C.''.

''Locomotive 5616 was Built at Crewe on 16th August 1934 & was named ''MALTA'' on 6th August 1936, she was renamed ''MALTA G.C. on 23rd October 1943''

Or the LMS Locomotive
Jubilee Class 4-6-0 No.45616 ‘ Malta GC’ (BR Green) (593)
