Clocks, Watches/cannot find time adjusment on clock

I have a Forestville mantle clock with two wind up holes; one for time and one for hour and half hour strike.  Recently I oiled the clock (had the proper needle type pen) but mistakenly oiled the gears instead of the holes in the back.  This clock kept perfect time before this but is now running approx. 10 minutes or more too slow.  There is no pendulum to adjust and no F or S or + or - to adjust.  Someone told me there is an adjustment behind the balance wheel but we cannot find. 1 # on the wooden block inside says H72 & a # on the movement says 3 slash 65.  We have no clock service person in the area.  Realize some of the oil is contributing to problem but need to find adjustment. Can you point an arrow in the picture we are attaching please.  Any help would be much appreciated.  Thank you Sandra and Richard

Sandra, I have worked on Forestville clocks before, but I cannot remember what type of regulator yours has.  I believe the 3/65 would indicate the year in which it was manufactured.  The adjustment would be from the back and I would need to see a photo of the back of the clock with the door open so I can see the movement and the regulator.  And if you can get a little more light on it that would help. It might be a floating balance regulator.  Usually there is a (+) and a (-) on the back plate of the movement next to the regulator but we'll see.  If you can, send the photo to my shop email address below and I can work with it better.  Also it helps free up the Allexperts question queue as I have a limited number of questions allowed per day.  Thanks.

Due to the number of Allexperts questions and
the workload I have at my clock shop, I regret
that I cannot answer personal email questions
on a timely basis other than Allexperts follow
up questions.

As much as I would like to offer values of clocks, I am not a certified appraiser and will not venture into giving an unresearched guess. There is very little published information on what I consider to be the value of "modern production clocks". Considerations are what the clock originally sold for, the condition of the case and movement, and particularly the area in which you live, the demand and the economy. ALSO, WATCHES ARE NOT MY FIELD. However, I can advise the clock owner on proper maintenance of a clock to keep it running, small corrections and adjustments and how to move a clock without damaging it. I can also advise on obtaining parts for clocks. It helps if you can send any information on the clock movement which is usually found on the back plate of the movement. I have been a clockmaker for about 35 years and was plant engineer in the mid 90's and later operations and engineering consultant at Emperor Clock Company in Fairhope, Alabama. I now have my own clock shop.


One of my greatest accomplishments was traveling to China to assist a clock factory in building clocks to the standards which we required. With the proper specifications and quality control, some beautiful clock cases were built. The factory people from the wood carvers to the plant manager were very congenial, friendly and I left a lot of wonderful friends when I returned from my trips.
