There is an online silat supplies store based in France that, on occasion, sells double goloks similar to this. I forget what the site is called but they do have plenty of pictures with double goloks similar to this.
I do enjoy modern Indonesian blades. For the most part they still make them with thick spines which I like. Until recently sold, I had a large golok with a 20-inch blade that was about 6.5-7mm thick at the base.
While I collect mostly Philippine blades focusing on modern-made pieces (With exception to old Pira and the odd kris here and there), I must admit that the modern blade market there is flooded with whippy, wafer thin blades that would not be safe to swing, let alone cut with. Regarding Philippine blades, there are still wonderful and incredibly functional blades, but you really have to careful about where and who you buy from and really do your research or else you end up with sheet metal that, I reiterate, is either too whippy or too brittle to be safely used.
With Indonesian blades of modern make, the quality of the average golok is much much better. I have never been dissatisfied with a modern indonesian-made blade as of yet.
This double golok is a good find in my opinion.
