And you believe every YouTube video that you see? If you were stabbing cross grain, maybe, but when you stab with the grain, no fibers are broken, and the sound still travels from one end to the other, uninterrupted. I’ll call BS on that theory. But if they want to prove it, go for it.

There is no such thing as a 3/4 viola. Violas are measured in inches of body length. Ie 15”, 16”,17”. They really don’t do a significant number of 14” violas, so it’s probably a chunky 4/4 violin.

If that fuzzy picture is the only one you have, no one is going to give you a definitive identification. The "repaired by" label doesn't help with anything. My guess is that there's about a 99% chance that it's one of the hundreds of thousands of anonymous fiddles from the Markneukirchen area from the first part of the 20th century. Also known as "the usual" around here.

Does it have a 440 pitch pipe in it? Rather than magic bullet, it sounds more like magic bull****.

If I remember roughly, a 7/8 violin is only about 3/4” shorter overall than a 4/4. Your grand daughter will grow through that 7/8 size in a shot! Build a 4/4 size for her, and it will be something that she can treasure and use for the rest of her life.

Are you doing the work yourself? That’s a really long crack! You’ll need lots of clamps to keep that aligned, and close it for gluing. Probably some kind of pillar and clamp system. For a proper sound post patch, you’ll need to do a bunch of fixturing and a partial cast to support the SP patch area. For the neck, a long dowel down through should do it. I’ve never done that for a bass. All in all, you’ve got a big job ahead.

I would think that trying to carve that complex shape, and still having it fit perfectly to the belly would be very difficult if not impossible. A waste of effort in my opinion.

I'm hardly an expert on this, but I'll just pass on my very limited experience. I was using a commercial varnish, and adding transparent iron oxides for color. It worked really well during application, but if I had any left over, it gelled within a couple of hours. Umber is a natural pigment that contains manganese oxide, and iron oxide. I would think that if you tried to cook it in, it might gel up immediately.

That’s right. Antique is “defined” as over 100 years old.

Maybe you got the price wrong. Should be more like 0.75€ or 7.5€ Looks like real garbage. Since it's a 3/4, it's not even worth using it as a tomato stake.

I wouldn't use it for dishes, except in an emergency. It come in 12 oz. pop top cans, for drinking. The instructions say "To use, open can and add 12 oz of potable water."

And if believe that, I have some dehydrated water that I could sell you at a very good price.

That would be my guess also. And the violin is also not that old, and not good.

The fact that it says "Made in Germany" gives an indication of date. Germany didn't exist as a country of that name until 1871. The McKinley Tariff Act of 1891 required labeling of imported items with the country of origin. It was amended in 1914 to require the words "Made in". In 1921 it was amended to require the name of the country be in English. This might put your instrument in the post 1914 period.

Any kind of oscillation or impact will be tough. This might work for you, especially since electric versions are available. https://www.google.com/search?client=firefox-b-1-d&q=carving+violin+chainsaw#fpstate=ive&vld=cid:6b0fc8a0,vid:X2n1W5THyGQ
