Those bigger images actually helped, so I think his specs are just fine. For example in image 1 measuring from back to front I got 35.5 and so did he, I got 3 1/4th for the remainder and I don't see that listed for his, going up from there on the front he has 30 and I got 29 7/8th's which probably the tape measure not being in there well enough.
Image 2 I got the same numbers for the width.
Image 3 starting up top he got 20.8 I got 21. he got 7.5 I got 7.7The next two I couldn't get a decent read with the glass and monitor so my numbers were skewed a bit. the 9.15 I had 8.6 and the other angle he had 26.25 I had 25.25 based of his lines he goes deeper then I did guessing with the curves externally. His other two numbers for the box were close to mine as well.
overall I think he has the correct specs, I had variance with molding in my way and not being able to get inside to get a good measure for those two but I think you would be fine.
Let me know your thoughts, I noticed he is missing a few measurements like the bottom of the CP, I have 13 and 6/8ths or so which is close to the 14 he had.
Also I spot checked my KI2 and MK4 machines on a few specs out of curiosity and I got the same numbers with them as well. If they made any real changes to the specs over the years it wasn't much.
