Heatsink nos. 1 and 6 are still available at $5 and $10 each plus shipping.
I am adding a three more to the sale...
Heatsink No. 7 is actually a set of four identical CPU heatsinks with aluminum fins swaged into a copper heat spreader. Just the thing for a multichannel gain-clown amp! The heatspreader is 89mm x 63mm x 6 mm thick. Overall dimensions including fins are 89 x 63 x 51 mm. There are 32 fins! These are unused and undrilled. They come with plastic covers to protect the fins. See photo in followup post. $20 plus shipping for the set of four. Weight is 4 lbs, 4 oz for the set.
Heatsink No. 8 is a medium sized tunnel type cooler removed from equipment. Comes with a fan and thermostatic switch. Dimensions of the heatsink without fan: 152 mm long x 145 mm wide (including transistor mounting flanges) x 80 mm high. The fan is a very quiet 12V DC brushless type, 80 x 80 mm. Transistor mounting flanges are drilled for 4, TO-5 cased parts and there are a few other holes. Black anodized finish. Length with fan is 181 mm. $20 plus shipping... unpacked weight is 2 lbs, 3 oz.
Heatsink No. 9 is a short tunnel, sort of thing. It has two Apex PA-12 power opamps and circuit board with a 115VAC powered fan. The opamps are mounted on copper heat spreaders and the heatsink is black anodized. This was removed from equipment and is untested. A tag on it says it is a model 250A DC power amplifier. Data sheet on PA-12 here: http://eportal.apexmicrotech.com/mainsite/pdf/pa12u.pdf
Dimensions are 120mm wide x 85 mm x 125 high, including the fan.
$20 plus shipping... (PA-12s sell for $98 each)... Might make a kick-butt subwoofer amp! Weighs 2 lbs, 7 oz.
