I love all the old ads in McGraw Hill's  "ELETRONICS"   Mag.   for  
components!

Micamold  and Solar Mfg Co are a bit of a mystery.  Both were quite well  
established companies up to about the end of WW-2. Solar, in particular, was 
a  regular advertiser in many electronic magazines.  Then they disappeared.  
I have an old Radio's Master catalog (have to wait until I get home to find 
 the date) that has Solar included in the index but with a note. There is  
nothing inside and a jump in the page numbers. Not missing pages, they were  
never there. It appears that the Solar reserved a place for its catalog but 
 never sent it to the publisher.  A web search brings no results.   
Micamold also seems to have disappeared but they did not advertise as much so  its 
hard to determine when.  I can find no advertising for the flat paper  caps. 
Micamold was involved in some heavyweight patent  litigation with (I think) 
Cornell Dubilier over capacitor making machinery and  with Aerovox. I can't 
find the details of the latter suit but it was evidently  very well known 
in legal circles.  I don't know if these suits had  anything to do with the 
disappearance of the companies.  Perhaps someone  out there has authentic 
details. 
Both of these companies  built all types of capacitors although Micamold is 
best known (notorious) for  the flat paper ones.
