That's actually too new for beta 1.7.3, as several of the textures have relocated in the terrain.png and/or been moved out to separate files. I'm looking one with a terrain.png that looks something like this (note the chest textures underneath the web):
Ah! So sorry. Completely overlooked the 'beta' part.
I've scanned through all my hard drives for my ancient backups and can't find my really old archives...moved somewhere safe no doubt, but so safe I can't now find them...a bit worrying actually. I've accessed my now fairly ancient MediaFire account and the oldest version of the pack that I can find there is still only for Minecraft v. 1.1, so post-beta I'm afraid.
It's bugging me that i can't find my old archive of texture packs as I'm not in the habit of deleting anything!
Real life has been in something of a turmoil this past year, so only now beginning to put some things back together again.
If I do find something I will let you know. Apologies.
