Dutch, you would still have sounded its internal size.

And with the zeros you do not mess up?

Since all zeros in order, and all sizes will certainly sounded tonight.

There's really bad at math, you should still add 2 to 17 (and maybe 3) :)

Very much a step pattern on the frame is constant for the XVII century. I have two Swedish wooden frame with a similar figure carving. True, the fine for the graphics. They inserted an engraving 1911 and 1918, and did not seem to have never taken out. Especially boring step alternation of bumps - in exactly one inch, while the other - 3 /4'. Machine work. But whether such machines in the XVII century - the question ...

Yes, the beginning of the 20 th century.

Outer dimension 48h32, 36h20 internal.

amendment.
Showed photos of frame antique dealer friend in Hamburg.
He laughed and said that yes, it is quite possible, and 17 th century, but only the basic tree, the material frame.
Frame old, and all that front, cover and paint are not very old.
Such technology was all the rage in 1900 - 1925 years. and is called the "piano-lacquer, black lacquer layered with subsequent polishing.
This tehnoligii, including engine performance in fitting the front part of the 17 th century to 300%was not.

Correction: lacquer there and not a penny! The whole front part - derevyaha! As iron, can not even imagine how out of it at all that it can be done. Luck is not even covered, just so polished frame. A technology "quick cutter" is just invented in Holland, which in fact distinguishes them frame this typical pattern.

I agree with you and this is at best ..
