Interesting bit about AIC, outback.
I have learned a great deal about Carl Monkhouse, including the fact that he came to the US from Germany in the 30's as WWII was inevitable. Big salesman and self-promoter, he produced razors from San Francisco and then to New York as he teamed up with Burrell(Case family) and produced Top-flights and CMons in Ellicotteville along with lots of surgical instruments for the War efforts. He also partnered with AIC for a short while. I have not found who his grinder was, but from the early ones imported by PJM pre-war to the various American examples through the 50's, The signature is there.
His grandson and great-grandson are still in Allegheny in the cutlery business.
The later ones simply had his name upon them as he sold it to PJM, who began to make them in Germany again.
A nice AIC is somewhat rare, but every bit a Carl Monkhouse razor.
