Dads Parker 10 Gauge

[Matto]

I blew up the Barrel picture and looked closer. it says 5 with a little 12 almost stamped right on top of the bigger 5. I am guessing that means 5 lbs 12 oz.
There is this marking near the 5 12 , (T) and a capital J and a 3 on the markings. There are also 2 other markings that I can't make out yet. but when I get better pictures in November I'll put them on for you guys to see. Is there any other markings that you guys need to see to help ID the gun and give it its rightful explanation?

I notice yours seems to have quite a bit more figure in the wood than mine, along with the dog's head buttplate, whereas my gun has the solid steel version. The dealer I bought mine from referred to it as a "Grade 0" (Zero) and even though it has some simple engraving on it, was supposedly Parker's cheapest grade at the time. He said the different grades were numbered back then, prior to when they began lettering them as DH, CHE, AH, and so forth. I haven't even started to research this and it's by far the oldest Parker I own, so maybe someone more knowledgeable will weigh in with some info. I'm wondering if the wood and buttplate may identify yours as a higher grade?
