If the '3B' is in the upper left corner, that would be the date code.....second week of March, 1965.
65-44467 is for Skylark V8 convertible.
TR 157 is the interior color... red vinyl bucket seats.
Body 'BF 629' means it was built in Fremont, California. It was the 629th Skylark V8 Vert built there.
Fremont didn't list the options on the tag. They put a reference number there, in your case #19867, that matches a number in a (long-lost) book that tells how the car was built.
There might be a body-build sheet tucked under the rear seat between the springs and the cover. They've been found in other locations as well.
Of the 2147 GS convertibles built that year, only 205 were built in Fremont.
