Re: I just found this forum, I got this Glastron v156 to restore
Hi Spectrabrite,
Have a look at on the right corner on the stern below the rub rail if you can find the HIN code (see circle), It starts with GLA and the last two digits are the year.....( 74?? )
You can also have a look here http://www.classicglastron.com/gl-the-years-web.html
Good luck on the resto and take some photos.
