Does anyone know what this pin is found at an old cottage that was built on an old cement factory the back of the pin looks to be made of brass possibly gilded and the front appears to be baked enamel no writing on front or back
I'll explain my post a bit further. I don't believe its military or at least not us military as most all crests or unit insignias I've seen have some type of motto or creed in Latin quite often. I think its merely a pin used to show someones family heritage or national origin....Scotland in this case.
I think you may be right, it may be a pin that designates what clan the person that owned it belonged to. The only picture I could find that was close though was the military pin listed in the above link.
