STB race pigeon timing clock metal mechanical 1960 Swiss

This is an all working pigeon race timer with mechanical clock made in Switzerland by STB. It has a heavy metal construction with winding key in the side. It could be locked for contest but now free to play with! When the race is one, the clock is wound and when a pigeon arrives the ankle ring is thrown in from above, the key is turned so a print is made from the exact time. Very cool and working, good condition leather strap as well. Parts like ink and the papers rolls are still for sale today. Now that is one quality system! Some signs of age and use on the outside! It measures ca. 20 cm or 7 1/2 inches wide. Check out the youtube video I found on racing pigeons!
