Hello Ben,
I've found, that if you wait long enought the picture eventually appears. Right, in answer to your question, there's no way you can improve the trigger guard form, it's already perfect.
Greg, Ben's picture appears to be a standard .45/70 Military action which someone has modified, by removing the sling attachment, rebarrelling and re stocking. I presume that because 'Scope Blocks' have been added it has been converted to some needle-blowing varmint calibre. lol.
My own Borchardt copy is progressing, albeit slowly. All the action body internal machining has been finished and I am now working of the external contours of the action. I am making a small number of special cutting tools I need that cannot be purchased. I am also planning making the Sharps style vernier sights.
Some four pages of pictures can be seen here:-
