What cut is this? RB or transitional?

[Rhea]

I have a stone from a 1920''s setting. Right now it''s set in a 3 prong setting. It has a very small culet, but looks like a RB. What is it? Don''t mind the fuzz and dirt in the photo.

Have a side view?

Not that I can get to, I''m not the photoshop genius that DH is. It has a low crown.

np... the lgf is in the 77% range judging by the arrows which makes it a modern RB.

The lower girdle facets are in the 77% range causing narrow arrows where in a older stone they would be under 65% and often much under making the arrows fatter.
