Hi David!
For a bit on the post-war HKs, take a look at this thread:

As well, for a good "guesstimate" on value, I'd like to see some pics, if that were possible? While the post-war Krieghoffs certainly don't command the market value as wartime HKs do, I still find them a fascinating variation(s)...
Best to you!
John
