Need suggestion for oiling an old strop....i suspect something light like grapeseed or almond oil perhaps?
Try some glycerine. Cheap in the pharmacy section. Works very well.
+1 for neatsfoot oilThe straight-razor supply shops sell "strop dressing". That's what I'd try, first. I've used it sparingly, and it seems to keep strops in good shape, so maybe it will work for restoring an old one.
Neatsfoot oil might be worth trying.
I'd stay away from vegetable-based oils (including nut oils), and _absolutely_ stay away from mineral oils.
I'm not sure how silicone-based oils would affect old leather. Might be worth a try.

So whatever happened to the OP?
