We had gas lights and cooker in the back of the house and electric in the front room , no idea why . Upstairs had one room with electric and the others had gas , we were terrified of the gas , this was a rented house after the War and we had moved to Northern Ireland ,it had been a boarding house and some of the tenants had installed the electricity . In Scotland we never saw gas lights at home but I remember my Gran in a Tenement in Glasgow had . Buying Gas Mantles was a tricky job
