I have no idea of the composition of Three -in-One oil in those old days but in the present day clock trade it is considered to be too short lived to be of any use. By short lived I mean that it dried out quickly. Whale based oils were the best! Their quality was based on the way they were prepared. Porpoise Head oil was the finest. Used in all fine lathes such as Watchmakers I have some left. David
