FODECO VIEWER NEGATIVE FILE, stuffed full of old treasure??

This metal file box looked interesting at a glance, then seemed a little heavy for its size. Turns out that it is a FODECO Model No. 166 VIEWER NEGATIVE FILE -- inside the lid seems to be an illuminated panel that could be used to inspect photographic film negatives, which are intended to be held securely in its bottom part that's fitted with dividers.

Yup -- that's a kinda cool thing -- I've never seen one of them before. Nicely made thing, it looks like?! BUT WAIT --

The potentially FUNNEST PART might be what the box is indeed stuffed full of. The paper label taped to its cover includes 'negatives of RR fan trips' and 'old snapshots postcards' on its list of what's apparently in there -- I've only barely glanced at the contents myself, but the front half+ does appear to be white envelopes with handwritten railroad names/places containing photo negatives, the back part is bunches of printed envelopes that seem to be old postcard folios from tourist locations, (places with trains?) and lots of loose photographs inbetween -- indeed nearly everything I've glanced at in there DOES seem to have some kind of railroad subject matter to it.

Pic 3 shows a handful of the postcard packets, pic 4 is representative of what the white envelopes are like. I predict its gonna take a little while to really look through all this in order to find out what's *really* in there -- first glances, anyway, would suggest it might be LOTS of fun to do so -- stay tuned for further updates! :-) ;-) :-) ;-) :-)
