[JMS] WA4IAM's Millen S/N List

[Don Buska]

Gary,

The large panel 90831 modulator we saw at the AWA conference several 
years back did not have an ID Plate (Variation 1 on our JMS website).  
Thus no serial number.  Besides the catalog picture of that variation 1 
modulator and the physical one we saw at the fest I've never come across 
one again.  Hey, maybe that was the only one in existence.

Speaking of model variations.  One of the old Millen brochure copies I 
have has a picture of a first version of the 90711 VFO.  It looks much 
different from the ones we all see as it has the standard Millen vernier 
dial assembly that has the large rectangular logging display.  Those who 
have older Millen parts catalogs will see this in their standard 
off-the-shelf offering.  That's something for us Millen collectors to 
always keep our eyes open for.  Items which may appear to be home built 
using Millen parts could be early manufacturer versions of  later well 
established products.  Then again I'm sure most of you are like me and 
can smell the Millen parts at swapfests from 100 feet away, hi hi.  I'll 
always inspect everyone of those red and black Millen boxes on and under 
the tables!

For me part of the fun working with the Millen stuff is that many of the 
products had some serious variations over the years, but the part 
numbers remained the same.  Like the 9090* scopes that went from 2X2 
tube power supply to using the later solid-state Millen module supply.   
They never changed the part numbers.  Probably more common in radios 
between 1930 and the mid-50's.  After that we started to see the suffix 
variations like A, B, C etc. added to the model numbers from all 
manufacturers.  Millens Grid Dip meter is a good example of later 
suffixing of model numbers.  I guess it's an indication of the 
advancement of modern marketing.  That "New and Improved" mindset.
