This may not be that helpful to the initiator of the thread.
But the Morgan 38 (1969?) is an entirely different design from the Heritage One-Ton.

I also believe there was a Morgan designed one tonner called the MORGAN 36T (1973).

Just to satisfy my own curiousity, I'm wondering if the Heritage One Ton is a later and different design from the 36T (as I believe it is). I know that during this period, the IOR rating for 1 Ton was increased, so that the average 1 tonner was longer by a foot or 2.
Since I have almost nothing on the Heritage model, I wanted to ask 'Nicholson58' for permission to use one of his photos of the Heritage on my site. (will PM).
I would also be most grateful to hear from someone who knows more about this.
Thanks very much.
