More goodies in the mail

I started playing Hordes of the Things with the idea that I could use all my old Warhammer Fantasy Battle miniatures and not spend any money on new figures.  So of course I saw something else on ebay I just had to have, so I spent more money on new (to me) figures for my skeleton army.

This mounted figure intrigued me.  I haven't had a chance to identify it yet, but the seller described it as a necromancer on a cockatrice.  Cool model, but I think I want to redo the paint job.

The main reason I bought this lot was for the skull chucker catapult.  I already have one of these, but another will make for some great long-range firepower.

The siege engine came with its three metal crew figures, and there were also more than a dozen plastic skeletons.  At $18 for the lot, it was a pretty good deal.  Only thing is, look how the plastic model compare to the old metal figure--it towers over the older mini. 

I didn't realize how much scale creep there was till I put these two miniatures side-by-side.  This means I probably won't use these plastics with my Nightmare Legion.  Anyone else turned off by the scale difference?
