|Keyboard from an IBM 029 Keypunch|
I came across a keyboard on Ebay that was from a data entry system that competed with the IBM 029 and 129 products, thus it was modeled closely on the look and feel of the IBM version. This is an excellent basis upon which to build my 1130 replica keyboard.

I will need to do some investigation once it arrives to discover how to identify keypresses, then build my interface logic to translate this to 1130 keyboard behaviors. Fortunately, there is a patent for the mechanism that provides some insight into its construction and use. The interface looks super simple to create. Further, the mechanism seems to provide the latching, need to restore and other characteristics that I want my keyboard to exhibit, so as to be quite reminiscent of the IBM 1130 keyboard. I have included a diagram from the patent here to illustrate the suitability of this keyboard for my purpose.
