I am currently working on ten Robert Adams Sceptre 21's from inner entrance doors to flats in Hampsted, as you can see from the pictures below they are in quite a bad way. Interestingly there are two different variations of the Sceptres in the same building on the same doors as you will see as work progresses.
As you can see the cams are badly worn and will have to be replaced, which then causes problems further along because these were hand finished and the squares filed to fit the recess in each shoe.
Nearly ready to refit.
Work to the guides of the adjustable top centres is also required.
As there is so little information out there with regard to door closers, especially vintage and antique model floor springs, I thought I would start this blog.
