We were criss-crossing posts for a bit...
I can find out, Lars... but you'll have to give me a few days. The airport is still in use for light aircraft, and AFAIK there is a pretty good local museum which will have archival records for the entire district. Did you know that there was also a camp for German prisoners of war at Gravenhurst as well? When I was young, there were still two of them buried there under immense, ornate carved wooden crosses. They've since been repatriated back to Germany, but I can't help thinking how much easier it was for them compared to OUR POWs... fresh air, good work, lots of food. No wonder so many came back here afterwards.
I'll find out what I can for you.
