...NOT!!!
thankfully the front of the fork-crown isnt really under any stress when braking, so grinding to correct this shouldnt be a problem.

Seems like they drilled it downwards. I'd ask if there's anyways you can mount it backwards on the fork, but that doesn't work too well with sidepulls, nor does it look very nice.

Could be somewhat exacerbated by an overenthusiastic crown race seat milling, in addition to being drilled crooked.

Wassa madda you? The hole she's a straight. It's a da fork crown that was tilted.
Send it back to the maker for repair/replacement.
I would NOT grind the crown race to fix that.
If you are going to take off material anywhere, grind tops of the washers until they slip under the race.

it's not a biggie, i'll grind some star washers and stack 'em.
but the problem is not the headset. it's the drilling. look at the hole centerlines (the lower horizontal lines), they are not equidistant from the crown race!!!

voila! just one of those funny "artisan" effects that makes each bike unique. :-)
here's a pic, post-fix...it's snug!

Problem solving 101. You haven't lived till you've worked on a Fiat! Can't wait to see her built up. I keep coming back and taking a look at your original thread, and I think I'd like to ride one of these for a summer or two. Have you found any other "little" quirks?

nah. drop-bolts are designed for BIG off-sets, not a few mm due to poor QC.
the rear brake bridge is neat -- it's not a single cast piece, but hand-made from a cast center and cut/notched/bent arms and "lugs" on the chainstays all brazed in place.
nice touch, no expensive tooling necessary!

You're welcome.
How about filling the misdrilled hole with heavily metal-filled epoxy and then redrilling it correctly? You could conceivably epoxy-bond a steel rod into that sad hole using epoxy to add some metal back into the affected area before redrilling.
You don't want to weld or silver solder as it will hurt the chrome and paint.

I wouldn't mess around with a defective fork crown too much.
Somec doesn't build that many bikes per year, do they? I'm surprised something like this got by them. Where did you get the fork from? Makes me wonder if someone's flogging factory seconds off on overseaers.

Again, your washer solution is fine. Go forth with vigor on your build.

this issue is done, i filed ~1mm from the bottom of the mis-aligned hole then ~1mm from the tops of the star-washers...that gave me enough room for stuff to fit snugly
the front of the fork crown doesnt see much stress, as the brake caliper tends to be pulled *away* from the fork when applying brakes. no need for filler or welding or anything.
this bike is from 1984 and i bought it from the 1st private owner after spending most of it's life in a shop window or store-room. back then, customers werent so discerning.

Mostly Mischief
Lots of advice here, some good, some questionable.. but clearly wallyman knows what he's doing, despite having only 48 posts. Sometimes in our close knit community we forget that newcomers can have as much or more experience than the resident experts.
BTW nice photo presentation of the now solved issue.
