I would bet this frame was made by Essex Arms for that company.
Yep. The blocky front strap is the giveaway.
The question is whether the slide is also an Essex. Cast frames generally fare pretty well as long as it's a good casting. Cast slides...not so much. Even Ruger...pioneer of investment casting...knows better than to use cast slides.
About 10 years ago, I built up a pistol with slide/frame set from Essex. The frame's specs were a little hinky, but I got everything to work. The slide cracked in the port, adjacent to the breechface about 10,000 rounds in.
