I believe these were marketed as 'Guild' or something in the US. Mine came off ebay about a decade ago and appears to be one of the first all-transistor models, cira 1966 or so. I believe it's the oldest piece of equipment that I use regularly - I also have an Akai 210GX which I use occasionally.
Most of my studio equipment is from the late 1980s or early-mid 1990s, when open-reel technology had reached its peak (microprocessor control, built-in DBX noise reduction etc).
