Here's a photo from the Lennon Museum book.
I have to go along with Mark's thoughts also. I'm seeing a two distinct grain features on the ramp that indicate this is the same guitar as the Bacon/Day photo (John's arm is covering it on the other), and two very distinct grain swirls on the upper body (above the bridge pickup) in all three pics, that seem to indicate that it is the same guitar in each of the photos.
As a side point. The brochure has photo's of all the Lennon related artifacts on display and indicates below each photo whether the item is a replica. There doesn't appear to be an issue of pride or deception. They freely admit that certain items are replicas. eg: (dare I mention it) Gallotone Champion - noted as "same model",
Sgt Pepper Military Costume - noted as replica, Gibson J-160E - noted as replica.
