These are GPO telephone parts. From my grandfathers collection of bits and kit from the 1960s and 1970s. This lot includes some interesting parts for collectors. It would be good to find them a new home with a collector of GPO memorabilia or a vintage technophile. Their working condition is not know but physically they are in very good condition. I think the receivers are GPO 700 ones probably used for testing purposes as they have small connectors on. 1 x Junction box GBO marked, 4A inside with code on back 95A.PXA 1x GPO (maybe 700 series) single receiver. 4T W65/1 4042W 1 x GPO 4T W64/1 4042H 1x unknown connector looks to be marked FHR 62
