Here is how a 1956 CE-100 would look like...

A pickup has been added, the original neck pickup was changed (the opening trough the top has been enlarged very likely) : a mic selector was added, an other control knob too (probably a general volume knob)...The pick-guard either is not original, nor is the bridge...(not to mention this very weird neck of course, as pointed out by Hans Moust.)
It's nice to have a Hans Moust's comment.
The link on Reverb seems more stable (guitar's on sale there too)
