I don't see anything pointing to any Panormo, but I am no expert.
The violin is certainly interesting though as the few things we have established so far don't really go together all that well.
You should try and take better pictures of the linings at the blocks or tell us if you can see it clearly. While I think they may be let in, it is but a vision in the fog, and not supernatural eyesight on my behalf.
The most interesting bit will be the neck attachment, as it is most likely original. There is no cut-out in the top plate.
The shape of the heel and the thickness of the neck towards the heel are also rather "different".
I wouldn't die of shock if it had a screw under the fingerboard, but that is certainly against the odds.
