That really isn't correct. Which parts would be "correct" for a particular carbine are fairly well understood. While no prime contractor made all of the parts for their carbines, they all used subcontractors to varying degrees - Underwood made the highest percentage of their own parts and Quality HMC the lowest - the parts were marked to identify both the company that made them and the prime contractor they were intended for.

For example, this is an original late war Inland carbine:

The hammer is marked I-I Inland Mfg. Div. for Inland
The sear is marked X.I. Robert Bobbins Co. for Inland
The trigger is marked R.I. Reece Buttonhole for Inland

E.I. Eaton-Pond Co. for Inland

PI Packard Mfg. Co. for Inland

A.I. Dayton Racquet for Inland

The extractor is marked W.I. Wadsworth Watch Case for Inland
The firing pin is marked I-I Inland Mfg. Div. for Inland

PI Packard Mfg. Co. for Inland

Stock and handguard marked OI S.E. Overton Mfg. Co. for Inland

Yes, sometimes parts were transferred from one subcontractor or prime contractor to another prime contractor to eliminate bottlenecks or shortages to keep production going, but the parts transfers weren't random or helter skelter and are fairly well documented. Many if not most of them are listed in the War Baby! books and in the Carbine Club newsletters. For example, on 1-21-1943 3,000 sears were transferred from Inland to Underwood. So it is possible an original Underwood carbine made during that time could have a sear that is marked for Inland. On 5-20-1943 500 operating slides were transferred from Rock-Ola to National Postal Meter, so an original NPM carbine made around that time could have an operating slide marked for Rock-Ola.

By studying known original carbines, which part markings are typically found on carbines made by a particular prime contractor in a particular serial number range has been compiled and recorded.

An original or "corrected" or counterfeit "original" carbine will have a collection of parts that conform to the known markings. An honest rebuilt carbine will have a hodgepodge mix of parts.
