[LargeFormat] funky plasmat

[LNphoto]

Since the LS is slow I 'd thought I'd throw this out to whoever was out 
there.

I was bottom feeding on ebay when I came across this

Now it came with a camera, which was worth the auction, so I'm not 
expecting much from this lens

but can anybody have a reasonable explanation why it looks like both 
cells are attached to the front?
Does anybody have any references about Plasmats?

 From searching post auctions I found (a much better) 9 7/8"  14 1/4"  
set.   Well the back cell looks like it might say 14"

but I can't make out the front.

I fear that the front cell is no more than the rim, but can't see any 
evidence of it.
