Hey Stephen,
Here's the skinny.
GEH is doing a Dead Link Removed wherein the conservation department (Ralph Wiegandt specifically) has designed an uber-cool housing that can be filled with argon, as described above, specifically to house some 1,250 Southworth & Hawes daguerreotypes. There are many volunteers who are helping to assemble these.
There's no way you'll be able to get a hold of one of these; this is an in-house, grant-funded thing.
Now, let's clarify what you mean by "frame". To me, that means we already have a cased dag, and we're going to put this in a sink mat, build a mount perhaps, cover it with a window mat and put this whole shebang in a frame with glazing.
However, it sounds like maybe you have a raw plate?? In which case, you want to have it cased or housed in glass.
Let me know what exactly you have and we'll go from there. If it's the latter, a raw plate, I wouldn't call this a frame-job and the kind of person who would have experience in this would be a conservator more-so than a framer. However, there's absolutely no reason why YOU couldn't do this kind of thing yourself, given proper instructions & materials.
