I never replaced the tag on my K0 after the sandblaster vaporized it. (old story) I checked Ebay and the net, I did a search but didn't find much hard info.
I see my current Ebay choices are Germany or India for the tag but information is lacking, The made in India tag shows a date but the ad doesn't mention getting a correct one. I wouldn't mind paying more to get it stamped too rather than buy a set of 3mm reverse stamps.
