Oh, my, that brings back memories!  That method of "encapsulation" was 
used by a number of Rochester electronics firms of the era.  It was 
developed by a good friend of mine with whom I worked at another firm 
about a decade before Spectracom was founded, and was introduced at 
Spectracom when he moved there.

It's hilarious now, looking at the crude PC layouts, the PC cards that 
look like they were separated with hatchets (in reality, they used 
heavy-duty, office-type guillotine paper cutters), and the "definitely 
not near mil-spec" hand soldering job using at least 5x the optimum 
amount of solder.  Spectracom didn't even have a dip-soldering 
operation, much less a wave-soldering system.

It was a much, much simpler time, one rung up the ladder from hippies in 
a basement....
