For example, both Auscab's PK 1892 of 1956, and my own PKA 800 of 1945, will cut 110mm deep, however PKA 805 also of 1945 (in Christchurch, NZ) will only cut 3 1/2" deep with an 18" blade.
I've seen it suggested on the Canadian forum that some PKs were specially modified for extra depth of cut. Whether that modification was to allow the full 4 1/4" depth, or whether it was to increase the depth beyond 4 1/4", I do not know.
Anyway, I would suggest that machining may have been to maximise the depth of cut on your saw. You suggest not?
