Nice progress, PM, and well done on cleaning up things like the ejector pin marks.
It's an old kit, a year older than I am, issued in 1963. For its time, it was a pretty spectacular kit.
I don't remember if it was released before or after Kennedy was assassinated, but the initial boxing was as PT-109. Revell re-issued it as several different subjects, and even a "McHale's Navy" version as the PT-73. The care you're giving it, you'll have a nice model when you've finished.
Best regards,
Brad
