#552 perf 11,
#578 perf 11x10
#581 perf 10
#594 perf 11, 19 3/4mm x 22 1/4mm Probably Not~!VERY, VERY, RARE!
Trying to guess perfs from a photo on the monitor is not the best, so you will need a perf gauge to determine the right one. I left out #596 due to the cancel. Hope I didn't miss any other. I suspect #578
