685. Model 237 (pre-Camper)

Now this model is known as Camper (1.3613), but no doubt, that specifically this knife didn’t have own name, – this one from epoch when Victorinox company used only numerical indexes for naming their models.
My assumption – this is model 237.
Are you agree with me? Any comments/suggestions?
(Pay attention to tangs on back side of blade and can-opener, – in my collection it’s a first knife with such combination)
