EMDE & Albion

[P3D emdesher <emdesher@xxxxxxxxxxxxxxxxxxxx>]

Judging from the volume of overnight emails, there's a lot of questions 
about my EMDE products and the Albion mask.  The EMDE No. 3300 aluminum 
binder was designed to be used with an aluminum mask (such as the 
original EMDE masks, now either out of stock/discontinued or with 
Stereo Realist, Sigma, or Albion masks) and TWO pieces of cover glass.  
It is the standard 1/8 inch thick so to fit the slide carriers of the 
1950's stereo slide projectors.  Use this when you want to project or 
give physical projection to the slide.  EMDE glass is due around mid-October,
and I also have anti-Newton ring cover glass in stock.
The EMDE No. 3400 aluminum frame is designed to be a rigid outer holder 
for the above masks and does NOT utilize cover glass.  The Albion mask, 
like the other forementioned masks, isn't really stiff enough to be used 
alone although I am sure some do use them that way.  There is a 
plastic sleeve made for the frame which will give physical 
protection to the mask-frame combination, but it is intended only for 
hand viewing, not projection.  Also, the EMDE No. 3400 frame is much 
thinner, and was not meant for projection uses.  If you don't crimp the 
top and bottom edges of the frame down (to really hold the mask tight) 
then you can reuse it.
The advantages of using an all aluminum/glass combination for projection 
and archival storage have already been discussed on P3D, check the archives.
The EMDE products are only available directly from me.  Contact me 
off-list if there's any more questions or if you want a sample.
