Terry,
You know, I have always been convinced that the HK mark was that of Krieghof but you make an excellent point with respect to the Krieghof Lugers & the anchor. I wonder what the source of Walter's conclusion that HK was really Heinrich Klein.
Regarding your two beautiful WFP bayonets, they're very desirable. In fact, I don't think I've seen a short model before these two. The logo with initials is definitely more scarce. My oly example is a long model but with stag grips.
