Multiple vintage electric guitars

[zzajlatem]

Hello,
I work at a music store that has old guitars hung on the walls as decoration. I have been able to identify 2 of them myself, but the rest remain a mystery. Here are some pictures
This one is clearly a Japanese Teisco, but what model?

This guitar is marked "Encore" and is similar to the one that Jack White plays in The White Stripes

This is a "Norma" bass

This one is marked "Decca" on the headstock

This one has no markings of any brand at all and I have not even seen anything similar

This last one has no markings either

Sorry about the way the images are cropped. The website that I uploaded them to in order to link them here did that.

I'm posting here to include more, better pictures. Seems most people who are viewing this just want to oggle the guitars anyway.
