Topic: Glass Bubble Vase - Is it a Keith Murray one?

[sectioned106]

Hi,  it looks similar to the vase shown on page 8 of Miller's "Glass of the 20s & 30s" as Keith Murray pattern 307A.  However, that one is 12 inches tall but this vase is only 8 inches tall.  Was a smaller version produced?  The colour is a dark olive/sea green.  There is a large round polished out pontil mark on the base - hopefully as photographed.
