I recently bought a NOS vacuum carb choke pull off it looks in good condition the vacuum holds. It has a number 12 stamped on the side of it I can’t find any information if most these chokes had a number stamped into them. I’ve read the divorce chokes have the last 2 of the part number stamped into them but can’t find anything on the choke diagram. Then there’s a small spot of rust from sitting in the box is there any way to re plate these

Just so you know that is not an actual choke. Its a vacuum break or pull off.
