NOS Knucklehaed cases value?

[duffeycycles]

NOS Knuck cases,long rib,no VIN stamp,bottom numbers are just 2 digits.
Were these 1950s production replacement cases?
What is the value of these?

The date codes will tell you when they were made. The 2 digit code is standard for replacement cases, they should match which means they are a line bored set. Full belly numbers only appear on complete engines. And they could date from the '40s to '50s. As to value they are likely about 5K if in new condition.
