Comparison of Blackburn (Swift) and Sunny Hill bottom metal for Winchester 70 375 H&H

[MaxM25]

With the excellent rifles many of you have could you help me out and describe the differences between the Blackburn (Swift) and Sunny Hill bottom metals for a Winchester 70 in 375 H&H? The two are not far apart in price and quality so I am most interested in details like trigger guard profile, finishing, and other aspects. Pictures would really be great to assist in choice. Blackburn (Swift) mentions they have a special distinctive profile but I have not found anything showing how it is distinctive compared to the Sunny Hill.

The Blackburn piece has a classic (and more handsome) guard loop. The magazine plate also has a slightly more rounded shape, which is subtle but adds to the appeal.

I knew Ted Blackburn and used to watch him machine these beautiful pieces while he opined on various subjects. Memorable guy.

As I indicated in your other threads on this subject, Blackburn (now at Swift) bottom metal is somewhat rougher and requires polishing and possibly tuning.
Here's Blackburn. Note the machining marks and locking lever for floorplate needs tuning. My Mauser Blackburn bottom metal also needed tuning for floorplate lock. Not a big deal though.

And here's Sunny Hill bottom metal. I don't notice much difference in shape.

Edit: Blackburn guard loop appears to be thinner width and Sunny Hill has longer trigger slot.
