Marks like that were not uncommon on penknives with nickel silver covers GT, and like the marks on your Schrade-Wostenholm knife, they deliberately reference British silver assay marks, which look visually similar, but are actually a complex code to where the knife was made, when, and by whom, example below from a John Cowlishaw Fruit Knife, Sheffield, 1836
Yes indeed

Could be Kaiser Bill
I'm not easily discouraged GT, but the new software makes it impossible to post threads like the scores of threads I've posted here in the past, and which are now scrambled and uneditible. I'd anticipated writing something akin to the thread I did on the River Porter, which would take several days to write, and would include a great many photos and images. I used to write posts like that in Word, and simply cut and paste them, but that's no longer possible because the new software alters the text in lots of ways, and there's also a degree of unpredictability, like the inaccurate character counts you mention. Text gets scrambled, and you can't even edit it because the system tells you (wrongly) that the text is too long or there are too many images. This thread is comparatively simple, but look how many posts I had to make, and each had to be re-edited several times. I can adjust to new software, but not when its inconsistent, unpredictable, and in my opinion, not fit for purpose
If you want to see blue, just include the consecutively type the letters U, R, and L!
