Old Bass Boat Info??

I recently was given a 1977 Imperial T-145 Bass boat by my father in law.
Pretty cool gift.

I've been Google-ing everything I can come up with to find a "spec" sheet on
this boat. I really want to know how much it weighs. It appears the
manufacturer has gone away or has been bought by someone.

Anyone know anything about this boat, or about Imperial boats? I know it's
not the super-bass-boat or anything, but for a guy who has been stuck on the
banks for some time, it's gonna be awesome.

Thanks,
Dan
