OSS Blued Pistol " Jack the Dog"

I see Jack the Dog is running an OSS Colt... does anyone know the quantity of blued variation compared to the parkerized finish?https://www.gunauction.com/buy/17197358

I seem to recall that approximately the first 3,000 of the 32 caliber pistols were blued. They switched over to the parkerized finish around November 1944. The vast majority of them were parkerized.

The Colt letter continued to indicate that the Colt Pocket Hammerless finish was blue after the change to phosphate, but still haven't observed a lettered OSS pistol in anything but blue finish.

I bought 1 gun from him and he undersold it. But that was 15 years ago.
