So was going through my grandfathers old garage and found some propert's leather and saddle soap which is FULL. hardly used. Seems from a quick google this brand was bought out in 1970. No idea what to do with it. Seem's a shame to use it, I don't really want to keep it in storage (Grandfather passed away) Bay only show's this via US sellers. And seems the tin is worth little. But as it's full maybe more. What would you do with it?
Can't imagine it being worth much... as you're Bristol way, perhaps take it down to Oakham Treasures and get their take... or just donate it to them: http://www.oakhamtreasures.co.uk/
