This is a red 93mm red alox Rancher, with the old swiss cross logo. It has an engraving plate on the front. These series were made for the Swiss tool shop Brütsch Rüegger.

0004 – Victorinox Pioneer Rancher
This is another gold alox model. It has no engraving on the back plate. As far as I know this means it is the one that is made for a Chinese Swiss Army Knife forum, and is limited to 300 pieces.
