Good results! Was the film brittle? So any edge marks to speak of?
Speaking of resilience, I've been pretty lucky with expired b&w film. For instance, I still get decent results from the plus x i use that was expired in 1965. I said good... Perhaps I should clarify, it is interesting and appealing to me! Colour on other hand, really old stuff can yield some fun results but more often then not it turns out junk - especially most of the expired fast film I've tried.
