Need HELP!

Back in the mid 1940's, the "Constructioneer" Magazine printed an article about my father and my uncle, E. Smith and Fred Smith, entitled "The Smith Brothers". They were Caterpillar dealers in New Jersey at the time, first in Irvington on Coit Street and then in Union on what was then Rte #29. Does anyone have, or know where I can get a copy of the article? Does anyone know where the magazines may be archived?

Looking forward to a response. Thank you.

I have contacted the present publishers and they only have issues from the last 5 years.
