Officers Service Dress Badges OSD

[Rob Miller]

I have been sorting through my Devonshire Regiment Officers badges to make a new album but I have a couple of questions first.

These 3 badges have very similar fronts, in fact I would say they could be made in the same front die, but the backs are all different.

1. Which of the three are cast and which are pressed/struck?

2. Which of the three are OSD rather than full dress or another type of uniform?

3. The third one has the stumps/remains of bendable blades, so is it a cap badge or a collar badge?

4. The first two are marked J&CO for Jennens, would you also attribute the third one to Jennens or has someone else cast this badge from a Jennens example?

All thoughts welcome.
