New Buck Algonquin 00hp3. Nominally 9.5x5.5x1". I was going to use these but then had the "bright" idea of casting my own (that's it's own story). These run about $50 each. If you can use all four, I'll do half price $100 plus $15 for shipping. Else $30 each, plus $10 shipping.
Located in the SF Bay area.
