Re-fit a Stanley 80 scraper with new blade-strap thumbscrews

I got an old one at an eBay auction, everthing OK about it, except that a previous owner lost one of the thumbscrews that secure the blade-strap to the body, and replaced it with an old brass screw and a square nut, oversized, for a washer.  I cannot tell the age or country-of-origin on mine, but it has the concave edge on the trailing edge of the sole.

These old scrapers, perhaps British-made, had paddle-style thumbscrews with a funky non-ASTM thread.  The newer ones that Stanley is selling today have knurled slot-head shouldered thumbscrews that have a "standard" 1/4-28 thread.

To drill out and retap is pretty easy, I think.  A #1 bit at 0.228 diameter, then the 1/4-28 tap, is all that is needed.  The 0.228 bit will take out the threads plus more in the threaded holes for the smaller British-sized screws.

Stanley sells the parts kit, two thumbscrews plus a new strap, and I've ordered it.  Won't do the re-fit until parts are here and examined carefully.

Anybody else done this?
