I may get corrected on this, but it seems Dikar, Jukar and CVA are essentially the same. My understanding is that CVA was originally of US manufacture, but then went to Jukar of Spain to have their guns made. Parts from CVA and Jukar are interchangeable, and I understand that Dikar is the same way.
I'm not sure of the dates (I'm sure someone here could enlighten you) that CVA dropped the Douglas barrels (US made) and went to a Spanish source. But if it says Dikar, you have a later gun.
Hope that helps
