Dang! I didn't think that would be it! 
Ok, now I gotta find something interesting....

By the way, here's the link to the whole photo of the flip-up viewfinder on the Brownie.

Sorry guys, I haven't forgotten the game, I just can't find anything post-worthy.
If anyone else has something to share, go right ahead. 

Bump.

I love this thread, what happened? It's been almost a month.

Me too. I ran out of interesting things to post, and no one has picked up the ball.
Also, having to link to images from online sources is REALLY annoying.
I for one find it difficult to overcome the mental hurdle of bothering with the extra steps involved, when it should be so easy. If the admin(s) would just clean out the old junk, we wouldn't have this problem. 

Anyway, hang on, I think I have something here....
Ok, give this one a shot....

spectrometer? Like, for determining the compositions of different gasses?

Negative, although it does relate to gases (or a gas) in some way.

Some thing to do withe plasma?

Possibly. I'm not certain whether plasma is involved in the process, but I wouldn't be a bit surprised.
Sorry, I know that's not really helpful. lol

It looks like one of the valves from an "old school' Marshall amplifier. .  Kinda

Nope, definitely not related to audio equipment in any way, although the amplifier part is oddly close....

Something to do with a laser?

Correct, now what exactly...?

No, no, no, I don't want to be the one who get's it, I have nothing good to post ...

I know the feeling!
I actually found one more thing to post after this one, but it's so obscure that it's not really fair.
I had to look it up myself to even figure it out. lol

A souvenir laser blaster component for the new Star Wars movie.

Haha no, but you could probably make something Star Wars-y looking from this. It would be a waste of an expensive part, though.    hint hint 

Glass tube of a CO2 laser.

Or, uh, part of a light sabre?

*Ding Ding Ding* we have a winner!
Correct, it's a lasing tube for a CO2 cutting laser.
Take it away Watcher!

Ok, this is either really obscure or immediately recognizable...
