Violin ID please

I'm seeing the C bout rib feathered in not mitered  which would be Mittenwald style, of course the corner blocks aren't. As to the scroll, it has a delta but the carving appears to go completely in, how is that Markneukirchen style

I see the scroll geometry, the wonky chamfers and irregular eye clearly in the Vogtland realm, while the depth of fluting can be easily altered. But as it is consensus, we can just wait if there will be more clues when it will be opened.

I didn't follow the whole thread, but... if, for example, there is no need to repair the violin that requires opening, checking 'what is this violin' justifies opening it?

Just stick an endoscope in to have a look around, much easier.

The suggestion was that it will need opening anyway to repair the soundpost crack

An endoscope won’t give you a birdsview of corner blocks and rib joints, unfortunately.

Since back plate was partially off the ribs I decided to show corners from that side.

There is a recess in a block (at least one).

I do not know if it's clearly visible but it seems those blocks are made of two different kinds od wood - one that fill corners (where recess occurs) and another one that cover that area from the inside and look to be a corner blocks imitation.

Strange.

Linings are not let into those blocks.

so you can see that they were blocks inserted AFTER the fact (i.e. not inside mould)

Yes, it makes sense perfectly.

So outside mold then? Post 1900 usual?

Very difficult to tell for sure, but the ribs still look like set with a mitre, not pinched together, and there’s no glue residue in the gap between block and plate. So they might have used some outside mould.

My understanding of BOB construction method, mostly based on your posts, is that the ribs are pinched/glued together at the corner before they are cut back. Therefore, the ribs must be practically parallel at the extreme end of the corner. How can the op violin be built on back when the ribs meet at such a wide angle?

With BOB, wouldn't there be more glue that would firmly connect the ribs first, and then gluing the blocks together? This work looks very clean, there is usually a lot of glue on BOB. Am I right?

one would have to rasp a lot of excess corner off

Sure, but my point is that to get the inside rib corner angle of the OP violin, you would have to rasp off the entire glue joint and more (red line). That would lead to a gap between the ribs, like in C. If you stop at the green line, you get B, which is a sharper angle than the OP violin. The corners of the OP violin have angles that look more like D, but that would not be possible with pinched ribs.

I get your point, still agree with BF that it is difficult to tell. One can "build on the back" without leaving the rib ends pinched looking

I agree when looking at the joint from the outside. The rib ends can be sort of chamfered to make the rib ends look thinner, as you have said before. This would also widen the angle at the tip of the rib corner, making it look more like built with a mold.

However, if you look at the INSIDE of the joint, I'm having a hard time picturing how you can pinch ribs to get a result like D (OP violin). If you have an explanation, I'm all ears!

Did some "schools" or makers also build on the back without pinching the ribs? If so, I guess the OP violin could be built on back.

[Blank face]

Especially in the 20th century there existed a lot of ways to make a rib construction look like something else. But I guess that the violin is originating from the Vogtland region anyway.

Are you aware of a BOB method where the ribs are not pinched?

I think there are quite a lot of regional styles that build on the back but using mitre joints.

Obviously Dutch and Vieux Paris where the ribs are set into a channel ...

I believe most earlier Neapolitan instruments, numerous Central Italians, many British instruments of the late 18th century. 

Probably there are others.

If one reduces the question to "Vogtlands built on the back", than no. But there are ways to disguise it, for example planing one rib very thin at the end would make them look like mitred from the outside.

At the OP it's by the actual photos not to tell for sure, as I wrote before.

Don't want to quote everyone here, just want you to know you guys are amazing.

I am grateful to all of you and I wish I could have some beer at least on me with you one day.

Maybe you try reading the label on the top block for a starting hypothesis.
