The taller one would probably be rotary press. That might make it a #545, which would be a nice score. Are the horizontal perfs 11 as well? or 10.5? on the left stamp. 10.5 would make it a #542, not a lucrative I'm afraid.
I agree with chasa. Left stamp is flat plate 498, right pair is offset 525. The intaglio (both flat plate and rotary) were 22-22.5mm while the surface print offset were 21-21.5mm.
Sorry cdnum. You are correct, this series is quite complicated, and takes more time. I was rushed in my evaluation (my breakfast was ready and I had to go ) I double checked your horizontal perf, and again you were right they are 11. Goes to show, if you can't spend the time, don't do the ... evaluation.
