need help with id of parker gun

[Hammer Gun]

I also believe it to be the 225.00 grade, although the gold cap on the grip is not there, the checkering on the forend is indicative of early high grades, and I believe I saw 4 pins in the reciever also indicative of the higher grade. A letter will probably not be available in that range the books are very hard to make out as per Mark.

The little I know about hammer guns I have learned from Gary and I believe he is right, but better pics of all the markings and of the entire gun is warranted to better assess the value or lack of.
