Restoring an early customized VM-68

Customer sent in a VM-68 that had been left to him by a now-deceased uncle, and wanted it reassembled and fixed back up. I'm guessing it had been customized sometime in the 90s. It had been stored in pieces for a very long time, and almost all the O-rings had dried up and crumbled. I didn't get too carried away with further mods, as it had some sentimental value to the client, but I thought it came out nicely, and shoots great!
