Pentax Spotmatic

The Spotmatic was introduced in 1964; it was the first camera with TTL metering that was sold in big numbers, the actual first TTL camera having been the Topcon RE Super. I bought the Spotmatic on eBay for £15.02, but I've not managed to get a Topcon (there are sellers in Japan, but they want £200, and there would be import duty on top of that).
