I followed ECNWC for many, many years and I don't recall ever seeing 1-10 (or maybe even 15). Several of the first ones he offered on the internet can still be found on Clips4Sale under someone else's name, I found "Bambi VS Thumper," etc and bought them but frankly they were very poor and not at all like his later ones. After watching several of these I actually deleted one, one wouldn't download properly and I didn't bother to follow up, etc.
I also found several of the 20's series at Rockin-Roxannes, and again one of the early ones was so poor that I started fast forwarding and I'll never watch it again.
