Here's a shot of the reverse of the frog which came on it. The frog is a late production item of rubberized canvas. Probably impossible to remove without breaking it, I believe it to be original to the piece too.
The knot I have attached to it is not original to the piece and is a Feuerwehr variant with a lighter pink than normally seen along with a different stem. Some of these knots come with cloth straps too, I love the variants of this stuff.
