The G137P stands for Grains 137 Powder. Which is about 5 drama
Interesting, with 4 1/2 drams stamped on the side of the action.
The heavier 'gun' weight suggests likely heavier powder charge.
The twist rate should be measured, which will tell us approximate bullet weight. Perhaps it is twisted for 480gr. PP bullets, not the typical 270 to 340?(just a guess on those)
It could be this rifle was made for heavier bullets than the typical .450EX., thus the 137gr. stamped on the barrels.
