Re: {Collins} Collins Serial Numbers

My 51F-1 1938 ish Receiver has a serial number 7603 -14.

We are pretty sure from the component parts and configuration that it is
serial number 14 of the 20 some 51F receivers made. 

I have other 30s pieces that have a serial number format that is  xxxx-yy ,
where the yy is most likely the serial number, and the four digit number
preceding it is some kind of model related number that did not change..
Now, the puzzling part of the question is what does this xxxx number refer
to.  I have original manuals for several of these pieces and they contain
drawings with drawing numbers but these drawing numbers do not relate to -
or include or refer to - the xxxx number on the actual piece of equipment.

We uncovered some late '30s documents today and notice some 32G serial
numbers were listed as "2878-1 thru 10".  The order number for the shipment
was 2878.  

Anyone have similar pre war serial numbered units?
