I recently bought the pictured clock at a swapmeet. It appears to be a relatively common Smiths bulkhead clock and, from its weight, it's solid brass! However, there's a bit of history with this clock which is that it formerly hung in 617 squadron's hangar at RAF Scampton – at least that's what the lady who sold it to me said. There's a date on the back of 1954 and also an Air Ministry stamp, so I have no real reason to doubt the story. Even though not from the wartime period, I thought it deserved a good home. It's in fairly good condition and seems to run well with a very sweet tick, except that it loses around 2 minutes a day with the regulator set hard over to 'F'. Now, I fully suspect that this clock has never been cleaned or lubricated in its life, so am wondering what the forum thinks would be the best way to go about getting this done. I don't wish to attempt this job myself, so are there any recommendations for a trusted repairer? I'm in the Grantham area, if that matters. Thanks!
