Greece, maybe, sure and why not, but there is nothing that suggests that its true. Other reading I've done talk about the Greek 4's coming through Belgium(all of them somehow marked) and being British
Enfields, less those references on this site by the same folks speaking of it here. Also, I've only noted one importer of Greek 4's, a US importer and as we know.... the whole thing would be marked up if that occurred.
I'll have to dig into export records to see if/what/when we sent them.
This fits as well, because there are no parts or marks that suggest anything other than LB and, if it was redone at LB 1950+, they'd probably have CA stamped and parkerized it.
The best part is that none of us will ever know for sure.. unless I can figure out that G2, maybe.
