Wallingford Bicycle Parts www.wallbike.com gives 6 months free trial on all Brooks saddles.
6 months test-ride!
I don't know of any other bike shop IRL or online that gives six months trial period.
No, you don't want a B17N. You want at least B17, B17S or even a B68. Don't forget there is a metal cantle plate under the outer 1cm of a leather saddle. You can't put your sit bones there. On a B17N your bones would be on the cantle plate, not the suspended leather.
Wide saddles don't really cause the chaffing, wide noses and too-much-pear transition are the big culprits. B17 is still fairly pear shaped. B68 is T shaped.
Let's assume the 143-150 you measured out at the shop is your center to center measurement. Your outside-to-outside is probably around 163-170. Add at least 1 cm to each side of that (for wiggle room as you corner and shift around, and to keep you off the cantle plate) and you are looking at a saddle with an overall width of 183-190.
Since 6 months is free, I'd start with a B68 (which is 210 wide) from Wallingford. Ride it a few months, and learn from that experience if you'd prefer a B17 (170 wide) or B17S (177 wide, but very short). Ride the B17 for a few months.
If my back-of-the-envelope guess for your outside measurement sounds off, do an outside measurement of your own, add 2cm to that (for the cantle plate) and look for a saddle that wide.
