Maybe something like a Datum or AstroData. The reverse code switch is for reading tapes backwards. It looks like a modified standard product. It does not appear to interface w/ a tape search controller.
At a guess it's mid 1960s to mid 1970s, to go w/ something like an Ampex FR1800 or similar tape machine. Many IRIG recorders could go 240, 120, 60, 30, 15, 7.5, 3.75, 1.875, and 0.9375 inches per second.
