If you can afford a copy of the Wisby book, all the drawings ( its standard practice to have a team of people doing exact scale drawing of all finds on an archeological dig both in situe and after removal. I did this on a dig on an 11th-16th century cicstertian monastery dig in England in the 80's ) are to scale and the scale is listed at the bottom of each page of drawings. Once you know the scale, a trip to Kinkos ( in the case of the gaugtlets ) and having them blow the pages up to full size and run off on large sheets of cardstock yields original plate sized templates including hole locations at which point you're 50-70% of the way there depending on what your building from the book. If working from the various coats of plates, used its fairly easy to calculate the conversion of the scale, so a ruler and knowing the scale conversion allows you to simply draw up the coat of plates plates from the originals by actually measureing each draw plate, and doing the scale conversion on the measurement. We did it with both Wisby gauntlets and one of the Wisby COP's. The scale listed in the drawing and a ruler will help you determine how much the plates overlapped as well. Don't know if this is helpfull but its how we did it.
