Seeking: X.25 networking equipment

Hi folks, I'm looking to build an X.25 packet data network for semi-active use at the Connections Museum in Seattle. Please contact me off-list (<astrid at xrtc.net>) if you have any X.25-capable networking gear (routers, PADs, cable, etc) that wants a new home. Why? Some of our newer equipment has serial management consoles. Plumbing those into a proper-vintage data network would be a lot spiffier than running around with usb-serial devices. I'm not looking for serial-to-telnet IP converters. I'm also interested in setting up a public federated X.25-over-TCP network, much like https://ckts.info/ but for circuit switched data. Cisco IOS 12 has support for DNS-based routing of XOT connections, which I've been learning how to configure.
