I'm looking for a vintage Old Rock or Deep Rock coticule with black manganese spots and lines. Preferably in the 5" x 2.5" size.

Regards,

Good luck with your hunt. They're not easy to find these days.

Old rock don't tend to have a lot of manganese deposits that I've seen. There's a 4x2" one on eBay right now for a $200 BIN, that is typical of how they look.

Good luck with your search though.
 
I agree. I love the Old Rock and Deep Rock stones for their 5x2.5" sizes; for manganese madness, I prefer the Salm Cotis. ;)

(Tho I've seen more than a few of the OR and DR stones that have the manganese lines.)

Regards,
Me
