I saw this for sale and it has some appeal....knowing very little about them and their history, I was hoping you guys could educate me about it.  The seller says its from the early 19th century and there are makers names label or logos anywhere.    Thanks!

This is an 8 day Longcase Clock with rack striking on a bell every hour, with moon faze, arch calendar with seconds hand.   The pillars design show this movement to be around 1800 to 1820, this also fits in with the dial, showing the minutes numbered every quarter hour. With this type of dial, they are called White dial Longcase clocks. With these painted dials, the less paint and good detail the earlier they are, dials that are heavily painted with poor detail the latter they are. The hands all match and are original to the clock. The hood of the clock is in the style of the Broken Arch type with quite plain pillars. Wide door that is correct for this period, the narrow doors are very early Longcases.  

It has some poor repairs, which I’ll point out. The one that bothers me is the angle of the pallets, which are sloping down, this tells me that the pallets could be worn; the escape wheel has worn teeth. Sometimes cowboys will remove the two pins from the pallet bridge, file and make the two screw holes into an oval shape,  you drop the bridge down to enable the pallets to have a deeper depth to the escape wheel, this causes the pendulum to have a better swing and to keep it going, to shallow and the clock will stop due to wear. This is a disgusting practice and will cause wear in other parts of the escapement. The bell post looks as if it has been soldered or glued.  The finger on the rack that drops onto the snail has been soldered.

With painted longcase clocks you have what is called a false plate, this plate is pinned to the dial and the movement is pinned to the plate, in many cases the plate will have to name of the company or forged the plate (note this is not the makers name of the clock)

Not sure about the wood but I think it is stained oak.

What is that mark on the dial just below the arch of the calendar?

thanks for  the great discourse!  I would not have notice the pallet angle.  Also thanks for detailing the reasons behind the dating of it, helps me learn.

I don't have access to it to examine the name, I was considering purchasing it but unfortunately i went follow to up on it and its gone!   Oh well, there will others :)

    • Many thanks for your advice (being borne in mind at present) & offer Dell. When I was given the clock the plastic anchor was loose on the arbour (it had split at the 'hole') &, after repairing this, I have been trying to determine whether the spindle (pin) should be perpendicular when the pallet is sitting on a flat surface; or whether, when installed, its L-R extremes (or alternatively its tick & tock points) should lie at equal angles from the vertical when moved with spring absent. I can get the clock to run but in every such configuration the top block has to be turned anti-clockwise (from above) by quite a bit in order to be 'in beat' & it always runs fast (despite the pendulum being set to as slow as possible). This makes me wonder if there is any particular feature of/fault in a torsion spring clock which determines which turn direction (if any) is necessary to get it 'in beat'; & whether there would be a different set of settings that would get it running nearer to time at somewhere around the mid timing/inertia position which would then allow tweaking of the fast/slow setting.
    • Now this has happened I bet China or India just to name two will start to produce none genuine parts.  I did. But idiot Boris Johnson failed miserably in his negotiations. The E U stitched up the UK like a kipper. Nigel Farage  offered his help but big head Boris declined. So this is why we are in this mess all because Johnson wasn't clever enough.  
    • Hands up all those who voted to leave the EU 😂, oopsie.  UK has just signed the Hague convention, next year that will provide cross border clout to British courts.
    • Ive heard about that oil before for the lever pins. I found it easy to work on , it didn't have a whole lot of pivot wear but i bit sloppy on the lever cock, i think you have to live with what you have or bin it. Stiff to wind and set ?  Not a cannon pinion issue that has no friction thats made up further back and if I remember the barrel drives the hour wheel. No problem on this one .Let me know when you start it as i have another that donated to this one, i can work alongside you with it, two heads are better than one.
