anybody ever run across a top like this? it looks like it was possibly a repair piece as the quality is better than most of the "cut piece of sheetmetal" tops i've run across. this one is formed sheetmetal & is spotwelded in numerous places along with the stick welds where the inner part was cut out of the main top shell. i'm going to try & replicate this cover for my other pump, as the original screw on insert piece is thoroughly rusted along with numerous areas of the main top. just curious if anyone else has run across one of these.
