An older Colins (1940s) often had a large stamp 1X2" or so from memory on the blade near the handle. The arm logo was part of the stamp. These were produced in the US if I recall correctly. I could not see any evidence of this stamp in the pictures, but the plastic did look like the material used in mass produced tools of that era.

certainly the original picture may be of a US Collins but the scabbard points, in my opinion, towards the ones made in Central and South America, there were many factories in these countries

I ma sure there were factories in Guatemala, Colombia and Brazil

I.P. and Milandro, thank you for returning the discussion to the machete!
As noted in Brinckerhoff & Chamberlain (1973) an image of a Collins type machete is shown (my post #20) and it is note that this firm was producing these from about mid 19th c. Naturally U.S. interests later in Central and South American countries would bring the firm to expand its presence into regions with such demand for these products.
