I have found this to be a very fascinating discussion and I have learned a lot. Researching the "Cecil
Opera" has actually taught me a lot about the relationship between the Edison
Opera, the
Amberola 1b and the
Amberola III.
Operas and the
Amberola 1b were both introduced in 1911, the
Amberola III was introduced in 1912. Clearly then they overlapped in production. And this shows from looking at the parts. They have the same gears and the same gear cover. They have the same motor.
They also had the same BEDPLATE. This is where things getting interesting. After the bedplates were manufactured they then had to be properly tooled for the perspective model machine they were to be.
An
Opera needed to be drilled for a horn/reproducer mount and holes put in to properly secure a id plate after the bedplate was painted.
Amberolas did not have holes put in the bedplate for an ID plate this, went on the cabinet. However
amberola did need holes for a reproducer mount. They also needed additional tapping at the bottom of the bedplate for a brass rod to help secure the amberol machine to the cabinet.
You may see the brass rod here on a amberol bedplate resting on a triump cabinet-

If you look closely you can see the brass rod helping mount the machine on a cabinet here-

You will notice the bedplate is notched so that the brass rod can properly rest on the bedplate. This clearly required additional drilling after the plate was made. Also notice the brass rod goes through a wedge shaped part under the bedplate which has been drilled to allow for it.
The wedges on
Opera bedplates did not have a hole. I checked mine. It has not been drilled for one. This would make since as this hole would be a waste of time to drill.
So what does this mean for a " Cecil
Opera". Inspect all bedplates closely, including underneath the bedplate. If it has any of the following features run!!
1,) Notch where a brass rod would have been
2.) A hole on the mounting wedge
These two things can only be explained by this bedplate being originally either an
Amberola 1b or
III. No
Opera would have this feature.
Look very closely at that area. If you notice repair work at that area and would be in the exact area where a notch or hole would have been assume there was once a a notch or hole in that area. If you don't see the mounting wedge at all, again assume it was removed for a reason!
Now onto the top of the bedplate. Look for the following
1.) a non authentic or missing ID plate
2.) a reproduction reproducer/horn mount
3.) the serial number on the bedplate should be clearly raised. I provided a photo of mine to show what this should look like. On a "Cecil
Opera" this will almost be flush with the machine as he had to grind this down in order to stamp the fraudulent id number.
Look for these five things. If you see any of them be very suspicious indeed.
