There is no markings on the machete , handles look like mahogany with steel and brass rivets , it's sold and heavy .
Look very carefully on the Upper left side of the blade about a cm from the top and 4cm ahead of the handle.
I have one as well but mine has the original reinforced leather scabbard with it. My blade is stamped with all capital letters about 3/16in high "LAREDO." The scabbard is stamped D.M&S Ltd 1944. It has been appraised by knowledgeable people at $250.
That Argentine bayo was scrubbed when sold out of service. A fair value would be IMHO around $150. If it had an intact crest then $225+
That 1907 refurb as is $35 -$45.
