Parker Hale Rifle ID Help

[Goopy]

Can anyone here help me with model identification of this fine old Parker Hale? Caliber is .375 H&H, but it has absolutely no model identification marks. The standard proof marks, caliber listing on top and Parker Hale roll mark on barrel but no model number...
Thanks in advance!

Thanks much, fellas. I didn't realize that I had posted this question 2 years ago- strange how the memory goes....
