I purchased a Solartron 7075 7.5 digit voltmeter from Ebay and decided to make some front panel modifications, firstly to replace the 5-pin input connector with banana sockets, and also to replace the broken handles. Once done I went ahead and performed a partial re-calibration using my own voltage source and HP3458a DMM as a transfer standard.
