I can respond on the AMS part. Post-World War II the AMS and DMA published
state sheets too (25K and 50K). I'm not an expert in this, and couldn't
speak to how far they got in completing the set, but for Maryland, it's
series V733 (25K) and V833 (50K).

Attached is a photo of part of the V733 index sheet.
