Someone just sold me a Brother 300T portable typewriter with carry case today. This model was first introduced in 1975 and was produced in Japan. The Brother typewriter I had has some old ribbons and needs a new one. The keys are still in good working condition. The unit has some rust in it and needs some cleaning. I checked the mechnism and it is still working. The roller and the keys still respond when I tried to type in it. It weighs 4.5 kilos and I bought it as scrap metal for 10 Pesos (0.22 USD) per kilo. The total I paid for it is 45 Pesos (1 USD.) I will just add this one to my other typewriters in my warehouse.
