308 caliber BLR with barrel stamp stating 358

I have a 1977 BLR chambered 308 caliber but manufacturer barrel stamp shows 358 caliber.
It is definitely a 308 and has been a good rifle. The wrong caliber was stamped wrong in the production line I guess.
Any thoughts from members if I were to approach Browning do you think they would want it out of circulation or want it for a educational piece? I thought I might suggest a new rifle if they wanted this one back.
Any thoughts?
