Thank you gents for your answers so far.
I am aware that Annie was gifted Lancaster's and corresponded with H.A.A. Thorn who was very commercially astute.
Annie also was given W C Scott's.
I have been given various measurements of guns reputed to be either Annie's or used by her and I have to say for a small lady if everything I have been told she was very adaptable.
That is why I would like a definative answer.
