Don't know if this post will help ..Glass Hawks were a spin off made in the early 60s...they were on Mfg hull..I was told by a local historian they made 3 or 4 models...canoe to 14 foot runabout..they were manufactured in Liverpool NY until there was a fire which destroyed their facility...they were sold through A C Lamb...this information was acquired by myself through Jim Brinson (owner of Brinson Marine...and member of Oneida Lake historical society)..Last year I was lucky enough to purchase a 1962 runabout 14ft...I have since restored it...very intrested if anyone else has one as this is local and rare being in production for only 3 yrs..if so send me an email
