This is a case in point of the dangers of trying to determine model purely by engraving. The current Ugartechea catalog shows the model 1030 with arcaded fences. Older catalogs show the 1030 without arcaded fences. One Ugartechea catalog shows the exact engraving on the gun you identify at as model 1030 on a model 100.

Here's another example. Based on engraving, what model is this Ugartechea? I'll give a hint; it's not a model 116.
