Greetings.
I fear I'm a bit late to the party. I see you've already done an excellent job of covering the ground for available cutlasses, and a frustratingly small ground it is at that. I do have a couple of thoughts to add, but I'll get to them later.
For now, I'd like to share three of my favorite internet "sword sites", though some of you may already be familiar with them.
The first is Sword Forum International. I know at least one of you is familiar with the place, as I've had a couple of good parleys with Red Maria there. I recall her telling us about the auction of Captain Tew's belongings, poor soul, may he rest in peace. I was able to find a picture at picture at Christie's of his elegant, if pricey, little strong box, but fear I never came up with a pic of the cutlass. Arrgh. To get back to the site itself I think of Sword Forum as "sword central" on the internet. The forums there have members from all over the world ranging from kids interested in anime swords to very serious collectors and scholars of the sword. Not to mention a couple of authors of historical fiction. Aside from the forums, there's a considerable amount of informational resources. The Museum Store there is an attempt by Adrian Ko and his staff to defray the costs of running the site, but the forums are by no means commercial. The store is there to support the site, rather than the other way around. If you see what I mean.
Unless you register, you will have a heck of a time getting to the forums without a treasure map, so I'll provide this clue for those who want to lurk a bit before they commit: SFI Forums. If you want to post, you'll have to register and are asked to do so with your real name (mine is Scott Bubar).
Here is a recent cutlass thread there inspired by POTC: Pirate cutlasses. Which reminds me, I meant to post that nice Butterfields "Caribbean" cutlass there.
The second site is NetSword. I love this little site, and have been a member for many years. Although the focus is on the European medieval period, all are welcome. The place is laid-back with a laissez-faire approach. There actually are moderators, but they're often off doing there thing for long periods of time (months), but the members do an excellent job of keeping the peace amongst themselves (usually). This site is non-commercial. You can read the forums without registering, but must register to post. Screen names are OK. (Mine is Sikandur,)
Lastly, there's .VikingSword.com. This is really two sites rolled into one: the Medieval Sword Resource Site and the Ethnographic Sword Resource site. And resources are to be had there in plenty. The forums there are for the true sword afficianado. The tremendous amount of edged weapon knowledge some of these folks carry about in their heads is matched only by the size of their libraries. But they're nice, helpful folks willing to share their knowledge, so don't be afraid to post. It is a non-commercial site. You can lurk without registering, but must register to post. Screen names are OK. I only occasionally post there, but when I do it is under my real name
