horn blanks, where to buy some?

I was vacationing at the Oregon coast, and brought home a wade and butcher crown vr near wedge. Lots of work to be done on this, including scales. It's pretty nice considering the age. I'm wanting to build some scales out of horn. But, where to buy some blank of proper size to match the lenght of the scales made for it.

Look at eBbay for 6x2 or 7x2 blanks in 1/8± (Iirc)

Maggards has 6x2x1/8" horn blanks for $9/ea or $18/set; only two of five colors in stock at the moment.

I buy mine on eBay or Masecraft.

Ebay usually, just make sure they are at least 6" long
