Jc huggins model 43dl-103.19820-22calsllr how old is it?

The J.C. Higgins M. 43-DL, Sears #103.19820, was a Marlin M. 81, tube-fed, bolt-action in .22 s., l. and lr. caliber. The ones I know had a unique, chrome-plated trigger guard, with a slightly different, "Monte Carlo" stock (notch at the top rear of the butt, and angled back in towards the barrel at the front), and they were sold in the late 1950's and early1960's.
