Original Hardware ?

[jh23job]

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 !!
