Wellands and J31s

[T L Jones]

Hi,

I have a Rolls Royce Welland gas turbine which I restoring. I am seeking
any information anyone might have that would help me, particularly
drawings. For example did the drawings that were sent to the US and led to
the I16/J31 survive?

I am also interested in the location of Wellands and J31s. I think I have
a handle on the nine Wellands that are in the UK but have no information
on any elsewhere in the world.

TIA
