Gentlemen, I wonder if any of you well informed folk could tell me anything at all about this newly acquired spike? It's 6/8, very hollow (about a 12 on the Henckels scale) and the stamp reads "Lindsay Mfg. Co. Pittsburgh Pennsylvania". The blade etch which isn't very evident in the photo says "Lindsay's Choice". I suspect that it's US made rather than an import, for no particular reason, but I have no idea about a date. Searching here and elsewhere has drawn a blank. Not especially pretty to be sure, but it shaves very sweetly.
