From the looks of the pistol in the advertisement and what little info I'm seeing online, the pistol appears to be strongly patterned after the Walther PP, albeit with 1911-like styling, a heel mag release, and an added firing pin safety.
The barrel, breech, recoil spring, pivoting trigger guard, thumb safety, and slide stop are all PP/PPK type. Also like these pistols, there is no external slide release lever.

A couple of the g00gle hits say made by Erma, EP-459 .380
That makes sense, considering that IIRC the last Erma centerfire pistols sold in the U.S. were a couple of scaled down Luger knockoffs that went off the market in the early 70s and seem to have been mostly regarded as gimmicks.
By the early 80s, AFAIK Walther, Tanfoglio, Star, Astra, Llama, and Beretta were all selling single-stack all-metal .380 pistols through U.S. importers or production arrangements, and Colt was selling the Gov't 380 and Mustang. I'm sure Erma wanted a piece of that pie.
