Cool! I bought the US version of the model shown in the bottom right corner from Sears for US$69 in 1976. A key for every function.

I still have my PR100 (top one) that I bought when I started college in 1977, it a little worse for wear but still works.

I have two of the ones on the bottom left. Great calculator as long as you don't depend on order of operations. Can't remember how much I paid for it back in '76, '78? Loved the way it did EE.

I had the "B" model in the pictures. I kept it from my dad for years, and then my mom threw it out during college because it looked broken. :-(
Really liked that one too...
