Congrats! Extraordinary find, especially given that some people search for these guns for years before finding them.
They must be old because they say made in W Germany.
They have a deep black finish and are only 17 numbers apart in serial numbers.
I never heard of one until today.
Both of your Korths are the Combat variant (rather than Sport variant), and both were made while Willi Korth ran the company, which he did from its founding through 1981. After Old Man Willi sold his company, the “Waffenfabrik W Korth” roll mark was changed to “Waffenfabrik Korth.”
From as best as I can tell from your photos, your 4” Combat appears to have the fully round, Python-resembling barrel shroud, which was used on the 4” Combat from 1976 through 1978. Its serial number should belong either to the 30### or the 31### series. Your 3” Combat appears to have the partially slab-sided barrel shroud and speedloader relief cut in the recoil shield, which were introduced in 1979. This Combat should belong either to the 32### or 33### series.
Given the proximity in serial numbers, one would expect the 4” Combat to have been produced in the 31### series in 1978 and the 3” Combat to have been produced in the 32### series in 1979. However, Korth serial numbers did not always progress sequentially, so this is just what one would most commonly expect. The proofing year is indicated by the two digits stamped on the barrel shroud just forward of the frame. I can’t make out either marking clearly, but it seems that your 3” Combat actually shows an “80” or “81” marking rather than the expected “79” marking, but perhaps I’m mistaken about that.
Congrats again on this remarkable find. If you ever wish to — and, of course, are once again legally able to — sell either or both of them and don’t have another buyer in mind at that time, please send me a PM.
