Thread: 'Tiger' 4-sided Paddle Strop

I picked up this 4-sided paddle strop recently. It's in very good shape, good enough I plan to use it for my work shave kit. It's marked '1912' in pencil.

But I need a little help with id'ing each side...
- Black Leather: not pasted, probably for finishing?
- Red Leather: seemed to be pasted, but is mostly clean now. Should I reapply some FeO2? (That's red, right?)
- Hard Wood: stained red, possibly from FeO2?
- Cardboard: I think, it's not wood. Can't see how this side would perform.

Thanks!
