I was quite impressed with the heavy brass frame type base of the last key 084 so with this key I thought I would try the same idea but with a more standard line up of ball race bearings and mountings and my classic small key dimensions, this hopefully will produce a medium sized chunky key with a fine action, I've also angled back the knob to smooth out the chunky look a little, the action feels very similar to how the keys looks, crisp and solid, its a very nice little key.
