I am wondering if any of you might know the value of a G&B 67 10-gallon visible pump. And is it a rare pump? I have not seen very many in the petroleum collectibles magazines. I have looked at some auction sites, and I have never seen that pump. Jack Simms books had G&B 67's in them, 5 and 10 gallon, but Jack noted that he wasn't sure if outside gallon markers were authentic. That makes me wonder if that is a rare pump. (This one does have original outside gallon markers). Hoping that someone may have some info. Thanks.
