This is from the "Carcano Page" website: ( Link ). Weights are at the bottom.

Assuming Tim is correct about the bayonet being part of the 7 lbs 7 oz rifle weight and that a folding-bayonet weights about 9 oz (from an auction site), then the bayonet-less Carcano weighed 6 lbs 14oz.

At that weight, one-hundred M91/38 Carcanos weighed 687 lbs 8 oz. leaving about 60 lbs for the shipping container.

The ad says 7.5 lb. Your posting. Bayonet is irrelevant. Removed afterward? Never there? We're talking original 100 rifle shipment. 750 lbs. FBI report, WC.

750 lbs in a 60lb container?

Still, that's about 810 lbs.

The 36" rifle weighs 5.5 lbs.

FBI paperwork suggests..100 36" rifles.

Klein's order form allegedly filled out by Oswald..36" rifle.

National archives rifle..40".

( P.S. A tip of the hat to Martha Moyer. And crazy John " I invented two Oswalds.. because...?" Armstrong, who is occasionally a good researcher...but a complete charlatan otherwise..)
