from 1940s on i sell a variety of new and used parts .Usually sticking to parts that i have personally fitted,over 35 years.All Fuels With Aga now a subsidiary of a USA firm manybpeople are frustrated about the "sell new only,trade in that old cooker" attitude. We like things that have worked for years , so i will do my best to help you keep that old range going and have parts from the 1940's onwards.My own Aga is a pre 74 (so that's 46 years old minimum) and our works one is also running on Electric ,and is ex oil from same era. We have very few used solid fuel spares, but many gas / oil parts and can still offer new conversions for that solid fuel Aga or Rayburn. Some complete cookers also in stock.Shortly to offer a conversion to ELECTRIC to fit various versions of Rayburn - but they will only heat the oven(s) and hob not water or rads! Do email your query -ideally with a photo or two -so i can help. Emails answered quickly! Barry Charman
