1 1/4oz, 3 1/2 dre. Or more precisely, the then SAAMI max of 10,500 psi loads.
Your gun was likely patterned with 1 1/8oz, 3 dre. If you had the box or the hang tags, they would tell you the patterning load.
I shoot a lot of Great Plains wild pheasants in the wind and cold and use both loads. As to whether those loads can be shot through your gun safely, I don't know, but I do know that Parker guns of your gun's weight and configuration were designed to shoot those loads.
See p.714 TPS for details including service and proof load specifications.
