George James ROBILLIARD before 1870 - Restoration please

[Bryan1]

Good day from a balmy 35 degrees Covid free in South Island NZ.
The photo attached  of the individuals is physical size 60mm x 100mm. It's sepia. If we accept the veracity of the provider it must have been taken before 1870 - that date of the sinking mentioned below. According to the record on the back of the pic purportedly written by the uncle of the left individual, the standing lad is said to be George James ROBILLIARD, born c 1851 to Joseph Robilliard (b Guernsey) and Elizabeth Loring-Bollen (Jersey). From family history I have no doubt of the veracity.
Wreck of the HMS Captain: this lad was drowned in that calamity along with numerous fellow mariners, not that her Majesty's government would have worried, despite the protestations of her sadness.
I would like to verify the "uniform" the lads are wearing.
I know there was quite an enquiry after this sinking. Any further information will be gratefully received. The photo is atrocious, I'm sorry. Disregard all.
Regards
Bryan

Hello Bryan

I'm not able to verify or give the info that you are seeking but I see that you have commented on the condition of the photo. Would you like us to restore it for you?

This CdV photo would need to have square corners for it to be a pre-1870 image. Sorry I can't help with the uniforms, but someone else may.

Hi Bryan

Can you go to your first post and add -' Restoration please' to it.   That way all of the restorers will see it.
