A new breakthrough in the dating of brass adjusters

I have for a long while been puzzling as to when the brass type depth stop first appeared in British plane making. My good friend Brian Jackson recently passed this plough plane by John Rogers onto me . This was quite a breakthrough for me, as it is the earliest plane to have this type of adjuster fitted that I have seen as yet. We have a definite cut off date for John Rogers of 1765. Prior to this the earliest example I had seen was by John Cogdell who finished production in 1773. I'm confident the plane has not been altered at a later date, and is in it's original state.
