Thread tapping – next size up from this hole

I’ve picked up a Record 4 1/2 plane. It’s missing the handle toe screw. Some googling tells me it’s a 7/32″ 20tpi screw, which are very hard to get hold of. (I tried a frog screw but they are too short). So the solution is to tap out the hole.
Would I be better tapping to 1/4″ UNC (20 tpi) or use 6 mm (which works out at 25.4 tpi)?
Many thanks in advance
Third try. The first two didn’t show up on the forum.
I’ll try it with no links.
Try eBay. The uk site has one now for £3.50 with the Brass nut.
In the USA, if eBay doesn’t pan out, contact Bob Kaune antique tools ( searchable) he’ll get you the right part.
And I believe the Stanley equivalent is the same thread. Make sure you get the correct length for the high or low knob.
Thanks Larry,but this is the small screw at the front, rather than the main bolt at the back of the handle.
No luck on ebay, or via the US. The part plus postage costs make it ridiculous, hence my decision to just re-tap the hole and use a “standard” bolt.
The one Larry has pointed out is the front bolt. I have a few spares but they came from different brands of planes, I’ll check tomorrow to see if they’re the same thread as Record. If they fit and you’re in the UK I’ll gladly post one to you.

So I checked and unfortunately the threads don’t match, sorry. Larry is correct however that the Stanley screws are the same because I check one of those two so that does broaden your possibilities without resorting to re-tapping the thread.

In the end I just tapped out to M6. Worked a treat as I managed to find a screw that looked almost identical to the original. And no-one will ever know!
