[Collins] KWM-2 s/n Sticker

[K2QDE]

After a complete inside-out, part/component refurb of my KWM-2, one item has 
me spinning my wheels: The emaciated silver serial number sticker (or what 
was the serial number sticker). All that remains is a small rectangle on the 
chassis. Any hints as to a source of an excepted method to replace that 
item?
I do recall online auctions of blank Collins serial number plates. My last 
resort would be a clear plastic label-maker strip with the unit's s/n in 
black, but I'm not sure that would stand the test of time (and heat). Any 
thoughts?
Thanks,
Stu, k2qde
