Finally found a "Pointing hand" stamped on a drop letter from Eureka, Cal. A "Returned to Writer, Unclaimed" type. It's a big hand, even has a cuff.
It looks like the lodge didn't know Mr. McKenzie's address, so I also get a straight line Eureka, Cal auxiliary marking, probably added by the post office.
I was going to add this to the rest but the site appears to be down (the up-coming move?) at this time.
