GRA-CO,

Have you consider manufacturing some other 1A2 Parts? If you are, here are some ideas.

Manufacture a KTU card cage or card shelf. Some people who like to add more KTUs such as MOH but the KSU has no more card slots.

Also make the bracket for the 118 frequency generator for the 551 as some people want a true authentic 551 KSU and do not want use to zip ties to hold the 118 frequency generator.

If someone can make the color buttons for the phones, that would be very cool.
