Funny thing: back in the day, when the big catalog retailers put their house brand name on products, buyers felt reassured about quality and service. It added to their value. Today it tends to detract -- who wants a cheap Wards rifle? That makes many of these rifles high-quality sleeper bargains.
Both Wards and Sears had rifles made to spec with FN Mauser actions. Wards had them marked with both the Hawthorne and Western Field house brands. I own an excellent Western Field Mauser made by Heym -- it's the one in this 1966 catalog page with the full-length stock (#4):
The rifle just above it (#3) probably featured an FN action like the Hawthorne, but I think the 760 had a checkered wrist.

FWIW, here's a similar rifle offered by Sears:
Is it worth buying one today? That depends on condition and whether you want one. It's likely an excellent buy if it's what you're looking for.
Price? Clean specimens tend to fetch under $500 today. Similar Husqvarna rifles of this vintage with FN actions also tend to sell in this range:

If the stock or barrel is thrashed and the action is in good shape, it would make a solid, economical (maybe $250-300) platform for a classic custom rifle. It's pretty easy to find shops that will rebarrel and/or restock FN Mauser actions.
If the whole rifle is in good shape, I suggest selling it on to someone who will appreciate it as-is. But I wouldn't expect to make money from the deal at present.
By rights these quality rifles should be priced double their current value, but we appear to be in a buyer's market for most vintage hunting rifles right now. I've picked up three in recent years, which is my bag limit.
