What's with this 6?, a factory six vin with a later front clip? Options

An acquaintance in our local PCA club emailed some pics of a supposed factory 6 a family is trying to sell after the death of the long term owner. I'm no expert, but if a 6 (and the VIN looks right) it looks like it has a 75/76 front clip on it. I'm supposed to get a write up from the son explaining the history. The goal at this point is to educate the family more about what they have and potential value. The front of the car is a bit of a mess.

Any advice on what to look for in terms of verifying what this thing is? I've suggested they look for the VIN stamping in the rear trunk floor, the plaque in the front trunk looks to be gone or painted over.

I've not seen any engine pics yet.

So the compliance decal and the A pillar VIN tag agree with the assertion that this is 9140430505. Look for the paint tag, and get a photo. Look for the Karmann body number in the rear trunk just in front of the lock; get a photo. If clear that is good, if not, try to figure it out; should be 130xxx where xxx is close to 505.
Next is to figure out where the front clip was welded on; it would appear that was aft of the bulkhead in front of the fuel tank.
Also look to see what the prospects are for returning to stock nose.
Check for the usual 1970 914/6 features: interior, guages, brake calipers in the rear, and so on. Can you get the transmission number. I can get the data for a CoA, but it sounds like the owner may have had one or had some documents with the engine number on it. To that end, what original documents are available for the car. If he had the car for 50 years, then he may have been an original owner, and had a lot of documentation; that can add some value.
