Does Glastron make aluminum boats?

I am currently looking for a boat to purchase and found one I'm extremely interested in. The boat is a 12' aluminum vhull that comes with a trailer and a 15 hp Johnson. However the title on the boat states that it is a 1984 Glastron and the HIN is only 6 digits long. I was under the impression that Glastron does not make aluminum boats, and after 1972 HIN were supposed to be 12-15 digits long. After some more detective work I couldn't find the HIN stamped anywhere on the boat. Any words of advice for this boat? Thanks!
