Almost certainly not the same as the California custom maker.
I find this by googling:

I don't know that "Royal Hunter" is the same as "Hunter", even.
One problem you have with foreign bikes is they may be VERY uncommon here, and people assume that because they are "rare", they must be valuable. Well, they may be as common as dirt in Amsterdam, so the rarity in the US doesn't necessarily equate to being valuable. You can imagine that some guy in Mongolia with a 1960's Schwinn might think he really had something, but we wouldn't get too excited about it.
My unexpert guess: Any bike with rod brakes that is more or less in working order is worth maybe $100-$150 in women's frame, $200 in men's frame, and then worth more depending on the condition. I don't think the "Hunter" brand would really be worth any more than a Raleigh, and if the parts are hard or impossible to get, might be worth less, especially if not currently rideable. If you had to start replacing tires, tubes, chains, rims, brakes, etc., to make it rideable, deduct that. Men's frame Raleighs in pretty good condition go for $300-$400 or so, seems like.
