Welcome Gordy, IMO, that script top is a pretty desirable top for the MS 80 certainly worth $500 if it is metal, straight and the inserts are useable. I do not believe MS 80s with the script tops were used with a globe. If a globe is what you are after, I am sure you could sell that script top and buy a regular top for the pump and have hundreds left over. Again IMO, I would keep the script top and see if it doesn't grow on you. Neil
