Jetlasers Ti pen

Hi guys, I just thought I'd share a few photos of my new (to me) J/L Ti pen with everyone. It's a low power, 20mW (30mW actual), 635nm version.
One reason for sharing this is that I have never seen one of these original Ti's before, and I assume many of you here haven't either.

As I understand it, this was the original J/L titanium laser; simply called the Ti. It is the only Ti that is a pen size.
Next in the series was the Ti-A, which now seems to be as rare as hens teeth; it also happens to be the one J/L titanium that I don't have. Hint, hint anybody?
Last but not least is the famous Ti-b that many of you either own, or have at least seen. Two of the following photos show a size comparison with the Ti-B.

This pen has the traditional momentary pushbutton switch as found on most pens, it also has a safety keyed tailcap switch with two keys. The tailcap end piece and keys are a nylon type plastic, but seem to be very durable.
One thing that really limits the safety aspect of this is that the switch can be turned on, and then remove the key with the switch still in the on position. IMO, not a real concern at this power level.

This unit also has an extension barrel for the use of (2) aaa 1.5V batteries, whjch is the only way that I've powered it up so far. I'm assuming that without the extension, you could power it with (1) 10440 Li-Ion 3.7V battery, but I'm not 100% surd how it would like 4.2V vs. 3.0V.
As far as I know, this laser came from J/L with that white & blue lanyard to hold the safety keys.

I recently puchased this from Whodunit13579. He's a great guy to deal with; the laser and the nice looking case it came with were both in like new condition!

Anyway, here's a few photos. Anything else you'd like to see just let me know.
