I have everything in the way or Narnia toys, and pretty much know everything as well. Not to brag, I've just spent way too much time on these toys

For LWW the was no comprehensive 3 3/4 inch action figure line. There were large and small static posed figures. There was a 5 inch semi action line, with only a few characters. There was also 6-7inch disney store action figure line containing the 4 Pevensies, Aslan and the Witch.

For the Dawn Treader, there was nothing at all.

The articulation on the first wave of Prince Caspian figures wasn't great. The second wave had really great articulation and sculpting. However, they are worth about $200 loose for the full set of ten figures. In the packaging they are probably worth closer to $400 for the set. They saw a very low production run worldwide.

Just curious, why do you want to give firearms to Narnians?

Thanks for the information. I really wish I picked up the Prince Caspian figures when they were in the stores. I am interested in using them with my GI Joe army and doing sort of a GI Joe VS Narnia thing. I am only really interested in buying Aslan and the four Pevenise children. I like mixing toy lines and seeing how they work with each other. I mix GI Joe, Avatar and True Heroes toys and they work well together. As for the guns, I think they need more then swords and arrows if they are to fight against Cobra.

For your purposes, I'd say the PC basic figures in green packaging you can still find on eBay quite easily are your best bet (although Susan, if you wanted her, will be a real challenge). I'm no GI Joe authority, but I'm guessing there about the same size and would hold your weapons. For LWW there were a lot of figures issued, but most as StBrian already said were static or had very limited mobility.
I looked at a bunch of my various figures from all the movies and most can't hold weapons. Their hands are either closed or have something already sealed in their hands. The largest size LWW figures in the maroon boxes like the Aslan/Edmund/Cyclops or the Peter/Otmin/Black Dwarf sets and the Disney ones StBrian mentioned are a lot bigger and nicer and I think make the best for play figures of them all and they can definately hold things, but they may be a lot larger than the typical GI Joe? They are also pretty pricy now days. There is a very early LWW set of figures that I only have Lucy and Tumnus of that are probably more the right size to a GI Joe but they are ridiculously hard to find (usually only on eBay UK) and they cost a lot!
And just for correction, there are a few Dawn Treader Narnia toys, though I doubt you'd want them for your purposes. They are also very difficult to acquire I have found unless you live in Australia. There is a set of four VDT toys that were released through a fast food chain known as Hungry Jacks. The figures you could get were Aslan, Tavros, Reepicheep, and the Dawn Treader ship. I have managed so far to get 3 of the 4 off the eBay Australia site. They range from $1-4 but international shipping will hit you hard if you're not local to AU. Sorry, no Narnia kids were in the set and the three animals' ability to do GI Joe battling would be pretty sad, given their small size and cheap creation as a happy meal toy.

Regarding VDT:

There are a couple of miniature PVC style figures as well, including Chief Dufflepud and Tavros. ( / - scroll down) These are also pretty hard to find. Reepicheep, pops up quite frequently on eBay, but the others are rare. They have zero articulation though and are only a couple of inches tall, but they're really well made.

I need to get those Hungry Jacks toys, thanks for reminding me.

Here is a cheap option for Susan, plus a variant colored Gryphon.

Griffle, do you have any details for a manufacturer or country of origin for these PVCs?

Also, how tall is the Chief Dufflepud figure?

Manufacturer? Country of Origin? Says "Produced by RDP Creative UK" on the back of the packaging. Does that help?

There's an email address as well: enquiries@rdp-creative.com

The Chief Dufflepud figure is about 2½" tall.

I had the action figures for LWW, and for the most part it was good quality. But Lucy's arm fell off the day after I bought it!

I like the faces they do look like the characters/actors. often the toys don't. I wish they didn't have bendable knees & ankles (epecially ankles) because the girls joints bend too easily so they don't stand well, plus they don't bend into a sitting position so I'm not sure why they made the knees & ankles bendable.

I will be happy with the rubber smell goes away Laughing
