Callahan- as the man said- ELG in an oval is the proofmark of the Belgian national proofhouse in Liege Belgium. At one time, everyone in Belguim except the Prime Minister was making PARTS for guns (or so it seemed). This guy made hammers, that lady made triggers, etc etc etc, and THIS guy put them together and sold them. Hundreds of producers, thousands of contributors. Most were low to moderate quality, low price.
