Remember that this was in the early 1840s, when brass was still very expensive. They used strips of brass riveted together for economy. Another really wonderful feature of these movements are the roller pinions. Each individual pinion in the lantern cages is made like a small arbour, and spins freely. This means that they suffer from little to no wear after nearly 200 years. Unfortunately I wasn't able to replicate these for the replacement fan (I would need a better lathe setup).JChttps://www.blogger.com/profile/09831757279235998895noreply@blogger.comtag:blogger.com,1999:blog-6995009067480606492.post-40823048956130422532016-01-14T03:11:11.404-08:002016-01-14T03:11:11.404-08:00Unusual plate design.
