Taking 26k for the lid.

Aussie Black Box buyers (and sellers) at time of sale were at ~14.2k: https://gladiator.tf/listings/60e7d57f3d2ed0397429b2e1

Sale is 26 + 14.2 + 2 + 2.5 = 44.7k

Sold at auction for ~43k: https://scrap.tf/auctions/QOZ8OC

Unsolds at 59-60k for 6 months suggests that is much too high.

Rounding and taking range 43-45k.
