I have a Remington 1 ‘noisy noiseless’ which seems to have carriage alignment issues, evidenced by a failure to print using keys at the extreme left or right of the keyboard/basket (such as the Q or fractions). There is some fore/aft play in the carriage assembly (not the rails, but the whole assembly). If I pull the assembly forward as I press a key, it will type using these keys but still not very clearly. From researching on the internet, there are references to the centre tie. There is a smooth bar which glides against the centre tie but I can’t see how this might be adjusted. I can see that three shims sit between the centre tie and the typewriter frame but I presume that there must be another way of adjusting how the carriage assembly sits? Any advice would be much appreciated!
