First of all, I took a magnifying glass to the tobacco tin and yes, it is an A. the engraving says this: "VOL. A.S.Co." So I think that means he was a volunteer in the "A.S. Company" of the Lincolnshire Regiment. Not sure what that means of course.
Yes, I will try to upload a photo. I've only just acquired the camera and whether I can get it to capture the engraving well enough is the $64,000 question

But I'll try.
I am going to follow up the other links you dear men sent because this is absolutely the first time I have ever found any details about my Radley side and I've been trying to do my family hisotry for many years.
I am SO excited and hope this link will be a lead to more discoveries. If he
was my great-grandfather, his father was Wilfred Radley but he could have been another relative from Gainsborough.
Now with grateful thanks I'll go away and see if I can get some decent photos of this tobacco tin and then comes the puzzle of how to upload it so you can see it
Back soon
Kind regards to all
Lynda Finn (nee Radley)
