This is the reverse cover for a consew 206rb-1. I left it blank so you can make your own markings.

I bought one of these machines that lived a hard life in a factory and the plate on it was beat paper thin from the reverse slamming down hundreds of thousands of times.

These will need replaced every so often with heavy use but its better then a busted one or nothing as the plastic softens the blow and protects the body casting from damage.
