I own two, a '43 LB and a '50 LB both have mags marked as cantom mentioned. Although there are no discernible ownership marks on the Greek rifles both had stickers on the stocks to whom they were issued written in Greek. Normal handling marks from what appears to be a lot of parading, but absolutely immaculate metal finish and bore. A mag could easily be swapped and any identifying tags or stickers removed, and it would be impossible to tell it from any other LB. I can't say for 100% certainty, but I would suspect the vast majority of them are CA FRT's of WWII surplus (classic green parkerization) or of late manufacture (1950). Brian ####, who I got mine from at BDL ltd. can likely answer any questions better than anyone else. Brian knows because he imported them.
