I thought I would not do a full cleanup on the Vimy Parker given its high condition. I found the extractor to drag slightly so I disassembled the barrel parts. There is grunge so they got an ultrasonic bath. I know this means inside the frame there will be grunge. Now the gun shoots flawlessly but I know I will succumb to opening it up and refreshing everything so it will be good for another century of use. What else can old guy do with idle time to keep the brain occupied? Well lots of things I guess but this is therapeutic for me and cheaper than a therapist
