Hi all,
It's great John that you are now able to post some results of your dig. I think it was you who asked me about Waltons.
(Maybe an autocorrect changed "French/Walton" to "French/Watson"?)
I am away from home at the moment so can't look out my paper files on the Waltons, to engage with the topic, but will pick it up when I get home.
If any of the Sunderland glass is from the time Waltons had it, it would be the first glass I have heard of that's been found. There's bound to be some under the garage in Newton-le-Willows (Lancashire) which stands on top of their long-standing site there but who knows when that would ever be excavated. Waltons made glass on that site (N-le-W) from early 1870s to about 1900 - exclusively, apart from a brief period of a year or so before they started. (From memory, until I can open my files again.)
