Fork advice

On my '73 Raleigh RRA, I have always had a problem with the fork. On both it and my previous '73 International, I had noticed a fork blade misalignment looking down at the brake bridge/crown lug versus the dropout/hub position. I got Raleigh to replace both forks. When the replacements came, the crown race must have been set for JIS (27mm) instead of the 26.4 ISO dimensions I needed for the Campy NR headset (from the International). Since it was a relatively new LBS in Iowa, they didn't have a fork crown race cutting tool, so I wound up taking them to a machine shop (at different times).

The machine shop did the International fork perfectly (even though I didn't know anything about the proper dimensions at the time... no internet back then.) On the RRA fork, they messed up and cut the crown to ~25.96mm (what I measure now). I got some shim stock and have always shimmed it as tight as I could get it, and haven't noticed any real problems with it. However, I would now like to get it fixed.

Suggestions? Tom Kellogg from Spectrum Cycles told me via email that they could braze the crown up and re-machine it. It would damage the paint so repainting would be required, and he didn't know whether their standard white would match or not.
