They ran out of brown paint??
Not getting current political, but I believe RustOleum still sells hammertone brown as per the best match of color. Problem is that it's not high temperature. So it will tend to boil or flake and rust off. Their various colors of "Rust Reformer" will take a lot more heat though, as will the various high temp paint on the market. Flat or Barbicue paints seem to rust faster than other paints due to their flat surface. Also noted at work, we are more rolling stuff with stencil ink - but what's being rolled is usually aluminum.
It's a nice little unit is why. It'll take a GLC lamp and has a nice form factor, only about 5" longer than an S4 Mini, and a whole lot punchier than the Mini, which has a crappy MR16 50w lamp.
There's a Boston based childrens theater company - Chamber Theater, which uses the Altman extensively in a rig designed to work in spaces from a cafe-torium to a 2300 seat road house. The fixtures fit nicely on the Leprecon dimmers, take up half the road box space of a real S4 and are pretty robust.
Agreed with Steve, until you have used one in good condition in a small space... you don't understand how good a fixture it is. Trauma might be from memory they are advertising only the MC' series of them for sale. That's the E-11 based crappy lamp version. But I believe you can still get the G-9.5 version on specific request, or easily convert and it is worth it. Even used to own one with an Iris installed in it... I know where this fixture currently lives and at some point I will trade something for it in getting it back.
Very interesting thoughts on why that color. Can you expand that history further?
