I had a SuperBritte. First read about them in a GunDigest about 45 years ago. Totally cool looking gun. One came along and I bought it. Neat gun which was very well made. I could not shoot it well to save my life. Never figured out why. It was so bad my hunting buddy suggested if I was going to commit suicide I would need to bring reloads, two would never be enough. Sold it to a Doctor outside Lexington KY.
About 20 years ago there was a bunch of them which were finished up and sold. Guess they had been stored in the white about when WWII started and were discovered. Since I already had gotten them out of my system I was not tempted. Hope you have better shooting experience with one of you buy it.
