Here's a bunch of wall tubes. The ones in the top row have an incuse diamond logo stamped into the head, the rest of them have "A.P. CO." incuse stamped into the shafts. All appear to be unglazed. The overall length of the bottom one is 12-5/8". I've been told that the A.P. ones are tough to find. How about $20 + shipping for the bunch? E-mail with any questions, thanks for looking. How about $15 + shipping (which should be minimal on these)? Now $10 + shipping!
