The IBM Model M is one of the best keyboards ever made.

Athrogh they're pretty durable, they may need some repair jobs done over time, especially cleaning.

My keyboard is a 1391403, made in Greenock, Scotland, in 1992.

I've customized mine with a 1995 made industrial gray case, and with Hungarian keycaps made by Unicomp in 2020. Originally, the board had German keycaps, and the standard beige case.
