Cheers Gary!
The Conan 11 is a typo - I do have that on the master list, just a slip on the numbered list so it's still 72 issues:
Conan The Barbarian
11-35, 41-53, 57-81, 121-129
72
I've shared emails with Duncan McAlpine a few times down the years - he was very complimentary about my research and at one point offered to add it to his site but then we lost touch. I think he's a very talented, busy man and spends less time on comics now than perhaps he did in the past. His site is great, but it has many errors. It also sometimes clouds the distinction between non distributed cents copies and pence priced copies, a common issue with all pence research that I've seen. In my world, there are only pence printed copies and cents copies. Cents copies which did or did not come to the UK, stamped or otherwise, are still cents copies. The non-distributed aspect is interesting historically as to why certain books were hard to find over here but, in my view, all books are now freely available via online mechanisms so it's a bit of a moot point.
Keep posting Gary. The fact that your collection numbers mirrors my list is further evidence of its integrity. Hopefully, the best (only?) online list in the world
Cheers, Steve
