Is there an interchange manual to cross reference the original hardware called out in a 1942 parts catalog for jacobs R755 Engines ?

The Numbers I have for the NUTS are: 466B, 456B, and 684. Would these interchange to an MS number, or ?

Also the special “thumb style” hose clamps are: 20000, and 90170

Any help would be greatly appreciated. Thank you !!

Radial Engines LTD in Guthrie OK. They will know, I'd give them a call. Great guys but since they are in business to overhaul Jacobs engines I'm not sure hope much info you can get from them. Worth a shot...

Air Repair Inc. www.airrepairinc.com. They own the Type Certificate for the Jacobs engines and do overhaul and maintenance on the engines. Not saying that Steve Curry at Radial Engines can't help but I would start with Air Repair.
