Could be a Morgan or a Strain, or another vendor, not sure.
Where'd you get these pics? Is this your whip?
I wouldn't know what to look for to tell the difference, a lot of whips can look the same, but the knot at the end looks like it could be a Morgan (juding by the three plaits vs. only two). Though Joe Strain does make the larger knots (as he did with my whip), I don't know of many people that have ordered them. So, I don't know, but then again, I'm no expert.
Still, nice whip nonetheless...
