The WAGL Pivoted Bail, with this large pivot in the middle, was introduced on the Dietz hot blasts in late 1935 and the pivot reduced in size in early 1936 to the pivot we see thereafter. So the large-pivot-bail lanterns are all rare.
The Fitzall was standard issue from late 1914 thru early 1918, so is not original. It should have a maker's mold mark on the back side which can be used to date the globe more precisely. Good looking job, Chris, thanks for showing it.
