SN 6 (or 9) here. It is on a . Other sixes (6's) have seen have been crudely engraved . . .backwards. . .upside down (9's) etc.
This SN does not match any of the creb 9's in my hoard. . .either.
Any ideas. .? Weird 9 or lazy 6. Unusual? Bad eye site on my part? Advanced crebitis affecting my judgment. . .? Common as dirt? Scarce as hens teeth?
Help and old crebhound out. . .
