[Milsurplus] Two Draw Catches Needed

[David Stinson]

Been trying to find a specific type of draw catch
for restoration of a WWII WASP Lear ferry service radio.
Looks like this:

Need two of them.  Seems all the modern stock of draw catches
comes from the same manufacture, come in two sizes and aren't
even close to this one.  I've looked all over the web and every
hardware store I can find in north Dallas.  
I've even haunted antique stores, looking for old boxes
or anything that might have one of these catches.
Anyone have an idea where I can find older cabinet furniture like this?
Thanks,
Dave S.
