Most of the things I have for the T-176 is shown on this page of my website: http://petrolianacollectibles.com/gb%20176.htm
I do have some more that is not shown on the site.
I need to note that my website is dormant, meaning I cannot add/delete/change anything on it. It was created back between 1990 and 2000 using a Microsoft program called Front Page. In 2013 MS discontinued supporting this program and with over 12,000 image on the site it was impossible for me to repeat it using another program, so it sits there just to look at. Some of the original literature is no longer available and when it comes to the parts, some of the prices have changes. Meaning, just let me know what you are interested in and I will let you know. Also, please send me your email address and we will correspond using email. My email address is: email@example.com.
