This is the top cover that I would like to have printed.  I'll use it to make a silicone rubber mold.
These are files of the part in various formats.
Well I only had the time to get one quote....  This from the supplier that has been doing work for my company for the last two years....  The cost? $350 !!! 

So scratch that idea....  Back to the old fashioned way...
Unfortunately I don't have time to show the steps to make my pattern but the photos are done so I can do it later...

On the next page I show the first almost complete replica.  I say almost because I still need to make the two pin battery jack that replaced the Fahnstock Clips in 1938.  (My version had both...)
