Bluepoint Whitworth tap and die set

[Heringer91]

Hey everyone,

I was wondering if anyone here knew a rough value on this set?

I was left it by my grandfather who passed away last year

Are the tools marked whitworth? Usually the box is marked whitworth

Yes

He was a mechanic in Ontario Canada, and taught auto to highschool kids before retiring, but built a shop in his backyard and did work in his spare time after retring!

He restored many antiques in his time, including a old old British motorcycle the priest at his church owned. I don't know for sure but I figure he had these with the intent of working on the motorcycle for the priest.

I am at work tonight but I can snap some better photos of each tap and die over the next day or two if that will help!

An ideal set will have dies and taps marked BSW in the coarse thread pitches and BSF in the finer thread. There are 5 sizes between 1/4 and 1/2.

Assuming it does have the sizes between and 1/4 and 1/2, what would you guys say it's rough value is?
