ROSCO Tang Stamp... Early?

[Bill-in-Texas]

Is there a progression of tang stamp styles that has been observed for ROSCO switchblades? (Is ROSCO simply the mark of the importer?)



And, what are the years of production under the ROSCO name, please?

I suspect this one might be an early one prior to the word "IN" being addad.

Thoughts?

Rosco is the mark of the George Rose Company-a US importer.
Prior to 1954, they sold Latama-branded stilettos. US importation was stopped in 1958.
