Shanks must have been a very diverse and very capable buisness. I remember as a youngster going to a local steam engine rally , and the landowner always had his Shanks Hotbulb oil engine on display, it was quite a large engine , so they must have had means of producing very large castings.
After the rallies finished , I never have seen , or heard of where this VERY rare engine went , hopefully it’s in someones collection.
