I'm not sure about it being some random German trade copy, though I'm not an expert. But according to the internet the German trade copies of his violins mostly had fake labels, trying to resemble the original. This one clearly states that it's a copy and the only reason the last 2 digits are handwritten is because the Albani in question lived only within that century so he couldn't have made anything at a date starting with 15 or 17, which obviously made them be able to print the first 2 digits on all the labels.

Now I see mentions of him making a violin in 1654, but that's all I found.. 'mentions' of it.. so it's not like that particular violin was one of the more famous ones (for one I haven't seen anyone refer to it by a name, like most famous instruments people tend to copy), which makes me wonder why would anyone copy that particular instrument, unless he has seen it in person. 

Also the wood appears to be pretty decent quality.. so I highly doubt this was some mass-produced 'cheap' violin.. looks more like a bench-made or a high end production violin of some small workshop. The pictures don't have enough detail to be certain, but the purfling looks to be drawn on rather than inlayed.. (I think I can see some shades of the grain passing on to the middle of the purfling and I couldn't see any separate grains of the purfling and in some places it also looks like the ink has some feathering... ) still not sure, since the pictures aren't that high detail. But that doesn't matter much, since if it's a copy and the original maker didn't inlay them, it makes sense to copy it like that   

Based on the general appearance I'd say it's probably no more than 100 - 150 years old.

Anyway.. none of this is really relevant as I'm just guessing here.. mainly trying to train my observation skills so I could be totally wrong on all of these points.. 

What you could try is shine a light inside of it or maybe even use a small mirror with a handle if you have one that fits through the F-holes and try to look for a second label in all sort of weird angle... Usually copies might have a second label belonging to the actual maker / factory / etc..  

On these pictures the purfling does look to be more real So yea, it's most likely inlayed. Still not much grain visible on the pictures, but you can sort of see the how they're put against one-another in the corners as well as a completely different color of the inlayed wood in certain areas. Also some of what I initially thought was grain continuing on to the pufling on the darker pictures, turns out to be small cracks in the varnish.

Here's an example on my violin of what I was initially looking for You can see that the wood between the two ebony stripes has a completely separate grain (perpendicular to the black lines) and it follows the way the purfling is bent. 

You can probably find something like this on yours as well, though it will be harder to spot due to the cracks in the varnish, but if you shine a light at it from an angle you'll see it better. 

Anyway, others might be able to tell you more about your violin, Fiddlerman runs a shop after all
