Hello Syd,
I've noticed a slight surge in 72nd decal sales in recent months and it really is time that I did something new in this scale, so, if the economics work out I might do a 72nd set or two (maybe reducing some subjects from the previous three volumes as well).
As to 1/48th, I don't see the same rising demand as I've noticed for 72nd and I think that 32nd sales have damaged the 48th WWI market considerably. Perhaps the Copper State models releases and the forthcoming SE5a from Eduard will re-ignite interest, particularly with the rising cost from WNW for their 32nd offerings. I might dip a toe in the water for the Pfalz....
