“Hi June…I ran into Burt the other day in Burlingame and he told me about
your site…Very Nice!
I have been metal detecting above Surfer’s Beach on the freshly mowed
bluffs and am constantly coming up with lead cargo seals in one area with
the letters O.S. on one side and A.O. on the other. I figure the O.S. is
probably for Ocean Shore (as in railroad), but I’m stumpted about the A.O.
I’ve found about 40 so far. I’m glad to share.
