Rolex 18238 Wood Dial

[thomasey]

Good day all,

I have been an avid reader of this wonderful forum which is full of sharing and knowledge.

I am considering adding a Rolex Day-date 36mm into my collection and has came across an interesting piece and would like to seek some expert opinions on it.

It is a Rolex 18238 in Burlwood dial (as the seller told me).

The model number engraved on the case is 18238SP instead of 18238.

Should i be concerned about the additional SP engraved on the case or does it give any other meaning to it? It is consistent with the other engraving.

And is there anyway to find out if the dial is authentic and if it was sold as the exact configuration?

Thanks in advance!
