Special gun evidently. When FN computerized their inventory, they found enough parts to make about 50 more A5s in Belgium. The manufacture had already been going on in Japan for several years.
I may very well be wrong, but it was my understanding that the A5 was never built in Japan. They were origanally built in Belgium, and then when Browning started trying to cut costs they were made in Belgium but assembled in Portugal. I do recall the story about them finding the parts and building a small batch of A5's with them though.
BTW, that's a goregous gun.
