Nice Churchill! Just a word of advice: I had one of those SPIKA shell-holders on my shotgun and after I fired a few 1 oz slugs, the shell holder kept sliding up the gun towards the trigger. I ended up returning it and bought another shell holder that includes a strap that wraps around the end of the stock, preventing the shell holder from riding forward.
