Unless you've got a lot of missing hardware, you may have better luck cleaning your hardware up.

I'm not sure how much luck you'll have finding imperial sizes in Denmark.

What I did with my first restoration was to buy a junker of a similar era. Stripped it down, cleaned up the parts, and as I rebuilt things and needed a screw, a post, a coil, etc, I had some spares to work from.

Just an idea - if you want new, that's fine. Just thought I'd share what worked for me.
