1950 streetcar

I purchased some back-date copies of CTT and, Bingo! In the Feb 1997 issue, I found an article on General Models Corp streetcars built in the 1948-1950 period. I have one, not in great shape, and previously I could find no one who could identify the manufacturer, era etc. I am not a streetcar/.trolley buff so I am looking to trade this item. Does anyone have any idea on value and/or lead to someone who might be interested in this streetcar? Car is missing the trolley pole and needs cleaning.
I have been back in the hobby for last 5 years, mainly operating trains for the grandkids and doing a little collecting. Thanks!
