Sherwin Williams mixed the stain. It looks like transparent. It is definitely Min-Wax. Are there dyes one can add to stain?
If it was "mixed", then it can be tinted
If it's Min-Wax, then no not really
Unless it was the Min-wax water-based stuff...that can be tinted
Are you talking the stuff you are using now?
If you are trying to match stain from 1967 there's no way to advise you from here
Christ it could be anything
Stain with shellac/varnish over it?
Even if you had the exact same can of stain, and the exact same can of varnish from 1967, and you put it over the exact same type of wood used in 1967, it won't match
The old finish is too well seasoned and the wood of today is different than the old wood...it'd look different
You may luck out mixing some stains, but it'd be pure luck... I'd suggest saving a ton of time, heartache, and money, and taking a sample of the old stained wood, and the new raw wood, to someone who can match it
If it's someone in a Paint Store or an antique furniture repair/refinisher
Pay them whatever...it's worth it
You may need to do some wacky steps to match it...like dying wood then staining, or staining then shellacking with a home-made shellac
There's just no way to tell over the internet
