I know that both Davo and Lighthouse offer hingeless pages for Indonesia (any other brands?), but I'm unsure if either offer spaces for the Vienna printings of 1948-50. I don't think Davo does, based on pictures of collections I've seen on
ebay, but I'm not sure.
I could always use a stockbook or T-Blank system from Lindner/Safe, but I figured I'd check and see if a factory solution exists.
Thanks.
