they are very cool speakers man, they kind of remind me of the smallblocks that Splawn makes. I haven't owned any Heritage Greenbacks or the pre-rola stuff, only chinese and some 2003 ones that were made in England, so my opinion is incomplete as far as a comparison. IMO, they have a similar vibe in the mids compared to a good greenback, lots of that mid snarl, with a lowend that holds together a bit better. Low wattage, so they get breakup pretty easy, bit on the brighter side IMO. I think they were only like $100 + shipping new from Wizard IIRC, but it's been a while. I used to go thru Josh at Rebelamps, but he doesn't carry Wizard anymore. The only used pair I saw sold before I had a chance to even PM the guy. Just for my personal tastes and greenie variations, I liked them a bit more than the current Celestion greenbacks, but not as much as the Scumback M75/J75.
