nefoundland sledges

I am currently working in the highlands of scotland thinning scots pine. I have made friends with a local contractor Ian cameron who is also a historian, author and chairman of the local town council in ballater. One of ians first book is [ plant&roots a social history of ballater ] it covers the newfoundland loggers who came over during world 11 to help out the british goverment in their war effort. The men were stationed all over scotland but my interest is in the logging camps in ballater. I am interested to find out if anyone across the pond has any knowledge of this and the possibility that there might be some of the newfies as they were affectionatly known still alive. The other info i am looking for is the construction of their sledges and if there are folk out there that know how they were made. I will try and post some pics of the sledges. The wood in question where the camps were situated is called dalmochie, it is on a very steep slope with very rough ground in places and i can not figure how they braked the sledges.
