Which Aneros is this that I have?

I have the very first version of the Aneros, which I got years ago....at least I think it's the first version. It doesn't look like any of the Aneros massagers that are currently on sale from this site, so I wondered what to call it!

The head is not very big - smaller than the widest part of the body - and right underneath the top of the head, on the same side as the front leg, there is an indentation, or a "dip". This Aneros also curves to the left on the same side as the front leg. The body gets wider about halfway down. Then it has the ribbed bottom and the regular handle.

Anyone know what this version of Aneros is called? I want to collect them all, but don't want to get one that I already have...though I guess that won't happen, since none of the ones in the Prostate Massagers for sale section look like this one. Just curious! Thanks
