mopar small block cast iron tach drive dist

Used mopar small block cast iron tach drive distributer. This came off of a running engine in a car I bought. I'm not sure what this is worth or how old it is but the tag has a 73 stamped on it so that might be the year it was made. It also has an aluminum collar on the shaft to stabilize timing in the upper rpm range. It worked when I removed it from the engine. It would be ok to use or it may have a nostalgia value to someone. I'm listing it for $175+shipping but is negotiable. It can also be picked up locally near scranton pa. Many new and used small block parts for sale.
