shure looks like green porcelain underneath to me

Thanks for the help. The top has a square about 4inch long that comes off thought that might be where the globe hold went?
It is not porcelain for sure I can scratch it off. Thanks again

Never seen one with a hole & not have a globe ring on it... maybe someone removed the ring & covered the hole, then u would just need a ring? Chris

I have seen a couple picture with other having the same thing on the top. it looks like me it was a plate to block it but not real sure. might top is polished and the peace is not. If I could get my pictures to work I would post one but its not working for some reason lol

If it's porcelain, here it is.

Nice pump. Mine is for sure not porcelain. I see why everybody thinks it is the color even looks right nut it is not for sure. Thanks for posting the picture. The is the same top peace mine has is that to cover up the option of a globe top? If not why is it there? Thanks Scott

The piece on top is where a pricer is clamped on. You can cut a hole in your top for a globe holder. Buy your holder first then set it on top and mark where it needs to be cut. You can also offer to trade your uncut top for a cut top. I did that because I hated to cut a good uncut top.

Thanks matt for the help and picture. Now seeing that I want to put that on instead. Now to find one lol
