GRISWOLD WINE PRESS NO.10

ANOTHER GOOD FIND-but I really know nothing about this item at all! it says no.10 grape & lard press on it! and a bunch of other things-griswold erie penn" etc"-im gessing thats ware it was made! I took the wood off the bottom of it. there was a buncch of writing on the bottom too! but if any body can fill me in on this item would be great! Is it worth anything-shoulod I clean it up? stuff like that! I look at alot of stuff on here and read most people say dont touch it-leave it as it is! im not sure why-but I wouldnt mind hearing about that as well! clean-dont clean etc"--thanks for looking and hope to hear anything about this thing! it looks like a old 1! thats for sure! thanks
