Can some one tell me how old are these gear and should they go to the museums?
These came out around the mid-70s. Burt was the name of the inventor and owner of the company. The company only lasted a few years.
There were 2 models. The one you have was the original and more expensive model. They later came out with a less expensive model which did not have the vertical back plate.
There was also a version of the model you have with stronger springs which was all black (anodized).
Remenber that these came out before ski brakes existed, when "safety straps" or leashes were still used on skis. They were seen as a huge safety improvement and very convenient. Problem was as has been mentioned here is that the cable attachement tended to break. It was a complicated process to replace. From a performance point of view the binding to ski contact was considered loose and sloppy.
