Hi All - I'm restoring a post-war (1948) Noiseless 7, and it is missing the shift lock mechanism. The Shift and Shift Lock key are in place, but the small 'latch' that should be attached to the shift key and "hooked" by the shift lock is missing. I believe I could fabricate one if I had a good enough picture or diagram to work from, but haven't been able to find much but a pretty vague line drawing.

Is this a common part to go missing, and can it be sourced? Or, is there any way a fellow owner could get close-up pictures of the part in question? I'd love to get this back to 100% (it's already typing quite well; carriage is a bit slow but functional)

Thanks, and go easy on me, it's my first post!
