"It is a commercial 98 but these should be Santa Barbara actions IIRC."
That was just one of the 98 actions utilized by PH.
They used surplus milsurp actions for many rifles, but the 1200 series, which is likely what the OP has, used purpose built "commercial" actions, without finger cut outs on the left side of the receivers. I've seen them with different adjustable trigger types as well.
Those actions were built by different companies in Belgium, France, Yugoslavia, and Spain. They may have even been built in other places.
Whatever, they are excellent actions and very well built rifles, no matter where the actions were made. PH did all of the finishing and fitting in the UK, to some very high standards.
