As Steve says, there’s no prospect of repairing the damage - the only practical solution will be the total removal of the lacquer and refinishing.

Luckily the veneer wasn’t originally spirit stained - just finished with nitrocellulose lacquer, so when all that has been removed and lightly hand-sanded (I’d suggest 240/360 wet and dry, used dry), the veneer ought not to have any discoloured areas. You need to be careful when sanding - the veneer will only be about 0.5mm thick (or should I say ‘thin’?). It would be kinder to use a cabinet scraper (NOT a paint scraper!) to remove the varnish than to use paint/varnish stripper. You’ll find YouTube videos on how to use and sharpen such scrapers.

Good luck with it Stuart.
