Okay....I see in the archives this came up once before (earlier this year),
but I have to ask about this...

The only question I have is the seller's mention of a US Stamp?  What does
that mean?  Does it legitimize this?

Otherwise, it looks like a British back saw to me (not that I am an expert).
'James Gregg, Sloan Square' sounds like British maker to me...  Thoughts?

I do know that a lot of my saws have 'spots of white paint' - I never
realized they were special identifiers that could increase the value :).
