At long last here is the dark purple/black grenadine fina #35. Although my shirt stripes and jacket are washed out, I think the tie color is pretty true to life on my monitor. Sometimes it appears more violet, sometimes more magenta depending on the light.Sorry for the delay, no work Monday for 15th Century War Criminal Day.
When I was asked where I got my tie (dark purple/black grenadine fina), I answered "Thailand" and the questioner thought it was a store called Tie Land. I figured that would now be my standard answer to where I get my ties.
I wear my Somerville with suits all the time in the fall and winter. They look especially good with flannel IMO.
They are balmoral boots, so they are more formal than the Northcote. But, as long as you feel comfortable wearing any bluchers with suits, I'm not sure boots would make much difference. I wouldn't wear anything with speedhooks or a commando sole with a suit though.
