What flash can be used with a Nikon FA?

The Nikon FA was an advanced amateur level, interchangeable lens, 35 mm film, single-lens reflex (SLR) camera. It was manufactured by the Japanese optics company Nippon Kogaku K. K. (Nikon Corporation since 1988) in Japan from 1983 to 1987 (available new from dealer stock until circa 1989). The FA used a titanium bladed, vertical travel Nikon-designed, Copal-made focal plane shutter with a speed range of 1 to 1/4000th second plus Bulb and flash X-sync of 1/250th second. It had dimensions of 92 mm height, 142.5 mm width, 64.5 mm depth and 625 g weight and was available in two colors: black with chrome trim and all black. The introductory US list price for the chrome body only (no lens) was $646. Note that SLRs usually sold for 30 to 40 percent below list price.
