If it was one of the 2 big spares sellers then yes it will be leather, both are reputable dealers who I have purchased from on may occasions, the "polished" side will simple be where it has been compressed into the mold or treated leather was used either way makes no odds, you'll remove the polished surface when sizing which will also help it saturate in the oil,, If using neats foot try gently warming it in hot water, this will thin the oil and allow it to penetrate easier,

I did wonder about the leather as it was a lightish grey and very hard, after soaking it for a couple of weeks then I wiped it off and there was no evidence of the oil having soaked into the surface at all. The outside looked as if it was polished and the inside almost looked as if it was woven. Synthetic leather??
Thank you will start again. Pity I have 3.
Cheers.

Just to say it was sold by a well known supplier and was listed as Leather. From memory it was something like £20.00
