Frosted Parachute Regiment cap badge.
 

I am not sure if frosted is the correct term but it definitely has a subdued finish. Is this unusual or how they were issued?

Could well be the known version of this badge which has a silverwash finish. It is not very durable which is why you can see the brass base showing through.

You can find some old posts on the forum about this.

I tend to just leave badges alone, it is just age, give it a wipe if you feel the need to.

this one has gone through the "wars", literally. and beyond ! mechanic, coalman.

An Air Drop coal delivery round, now that is a sight worth seeing. Free drop 56 lb sacks of coal at the end of each road followed by a stick of burly paratroopers to deliver them to the door. That should keep the housewives happy

Thank you for posting.
