Grandad's tool chest

I always thought the mysterious chest in the garage was my Dad's.
Last week Mum said it was Grandad's.
I never met him He was a pattern maker. Died in 1940.
Weren't allowed to touch when we were kids.
Never saw the tools used.
After bro died, and he'd never used them, they cluttered the garden shed at K's.
So I've brought them back.
Sort of nostalgic. But shouldn't I sell them?
