As a prof photog with a long history with old cameras, I'm quite familiar with it. Either your recall of the model number or your year is wrong as the camera went in production in 1966. The model that came out in 1959 was the SR-1.
It was innovative as it was an TTL meter which allowed the meter setting to compensate for whatever speed lens was attached. It was 12 yrs ahead of state of the art Nikon models.
My sister had one and when she visited the Grand Canyon in 1970, it was her camera that worked when others failed. For it's day, it was the reliable chevy impala.
However my love of old camera aside, I'd be hard pressed to want to use it in this day ang age to get well shot images. By now, unless it was cleaned lubed and adjusted on a periodic basis , the condition of the camera's shutter is mostly likely worn, the lube has dried out, the light meter is more than likely way off calibration or gone. Hopefully, the batterywas removed, 'cause if it has not been removed for years, it could have leaked and caused corrosion.
Incidentally, the metering circuit is dependent on an obsolete mercury battery. It may be replaced using a zinc-air hearing aid 1.4 volt battery, which usually comes in a six-pack and is not very expensive.
"There are many internal mechanisms that may fail on a forty year old camera, and the SR-T 101 is no exception. The only serious trouble is related to the exposure meter movement itself, in which the tiny coil tends to break, this situation requires a replacement. The back door rubber sealing foam will usually need replacement, and so will a small strip of same cushioning the mirror when it goes up. A strip of this may be cut from a similar sealing material from a hardware store. All other problems are easily put right with a minimum of effort and tools, unless the camera is worn out, which rarely happens. In fact, anybody who figures out how to remove the top cover without causing any damage may repair it oneself.
