After a process of elimination where service is known for a Charles Parker from Manchester I have 2 candidates - which may or may not be right.
1.

CWS Roll has C Parker as employee. May be CIS?
Unamed MBE sold at same auction Lot 73. Trio was 73A. I asked if it was the same seller but they didn't respond. What a shame if the Civil Gong has been seperated from the Service Medals.
