Can't price the pics here at work, could try at home.
Reaver - plastic weapons aren't worth much, but... those two metal close combat weapons. Strip them, ebay them. Can go for silly amounts sometimes, I wouldn't be surprised to see £10 each. Reaver itself not sure, can find out.
Levithan, clean up, ebay. Again can go for a good amount. Without being at home can't tell you about the rest, is the cyclops complete? Other tanks are shadowsword, stormblade and stormhammer.
The three russ are the nicer 3rd ed ones, I wouldn't ask for less than £3 each, they routinely get more. Hellhounds are very common and one isn't complete. You have 4 1st ed basilisks which go for a bit more than the 2 2nd ed basilisks. No idea on the 3 gyrocopters. The 2 thunderbolts are I think the rarer 2nd ed ones, but they don't go for that much, can't remember exactly.
Put the knights on ebay. They can go for silly amounts, but note one is missing its weapon, that big gun belongs to something else, I can't work out what though.
The Thunderhawk might go for £5-7 because it is missing all its bits.
The 2 warhound legs are a bit too random for a bring and buy, ebay as well in case someone out there needs them for repairs.
The Rapier is niether here nor there.
The 4 manticores are 1st ed models and fairly common, plus 2 are broken.
Do you have any pics of the plastic troops? if they are the ones with variety instead of mono pose infantry they can go for a fair amount.
Which era of metal bikes do you have?
Automatically Appended Next Post: But 3 tempests 1 wave serpant a couple of web spinners. Is the blue thing on its own a new wave serpant. +a warlock titan.
Last pic - packet of metal fire prisms could go for a fair sum. The 4 metal warwalkers are fairly rare (to the extent even I may not have them

), the plastic dreds are not but still sell ok, Warlocks again are ok, you have then got 3 1st ed tempests which can sell ok, 3 2nd ed nightwings fairly rare, 16 plastic falcons are ten a penny, the two 3rd ed night spinners aren't that hot as a two (not three), 4 phoenix fighter bombers also not that hot, 2 2nd ed doom weavers, 2 2nd deathstalkers, 3d 1 second ed firestorm which can be quite good, 1 2nd ed waveserpent very common, 1 3rd ed wave serpent incomplete and finally 2 2nd ed thingies I can't remmeber off hand.
Again can do average prices tonight...
