In general, it should be pretty close. Stanley was well known for buying out other tool manufacturers and then continuing to use up the existing parts inventory, changing the designs as their parts ran low and their production was brought in line with their other factories. That is one reason why so many of their early tools carry a variety of markings on the individual parts and why there are very limited production years on some of their tools. English produced Stanley tools are from a more recent era and they were more inclined to be more standardized with their other producers. Also be aware that many of the Stanley designs were widely copied by various manufacturers to  the point that parts are many times interchangeable and many a previous owner has swapped out parts as the need arose. That is why you can often find tools with features that indicate different production types or even different manufacturers.

Have fun
