Hi Michael,
Thanks for the greeting, and your optimism. After contacting Classic Fasteners in South Australia, whom I was certain they'd have what I was looking since they have the 7/64 listed in their British Whitworth list.
They didn't have the 7/64 in stock and don't where to get them but they did offer me the 6 BA, which on paper, looks like it'd do the job. When I got them I checked their major dimensions and they are smaller than their listed dimensions which makes them unsuitable.
The 6 BA is listed as .1102 but the screws came to me at .1050 this makes them a little loose.
I'm starting to think 4G UNF might be worth a try. But is this used on old British machine tools?
