Anyone know the original mast manufacturer for a 1979 Newport 30-2?

For the life of me, I can't seem to figure out the manufacturer and specific model number for my original and current mast on my 1979 Newport 30-2. I've been to the rig-rite website, and my dimensions and shape don't seem to match up w/ anything listed. I've spent countless hours of google searching and have come up empty. It'd be helpful to know the manufacturer and model # as I plan on going through my entire rigging top to bottom and I'd like to pick up as many parts that are a direct fit as possible while minimizing any custom fabrication or fitment. The width appears to be about 4.25". Length about 7.75". Circumference about 20.5". And it takes 3/4" internal flat track mainsail slides. Thanks!
