First run of new GOLLUMs and of 2 WMO RRs. - This GOLLUM set is called Bilbo even though 1 of the old Bilbo cylinders has been swapped for an old Frodo - Measured 2 other WMO RRs from this cycle in Nov/Dec 2019 (CC498886 and CB12416) - on 'b', noticed WD fail and had stopped purging after first up (11 purged, but then not 10), so restarted as 'c' and seemed to work - problem appeared to be fixed by stopping and restarting VB, so potentially software or PC related
