Hi, I'm hunting for the Chulung (NI 43-4) sheet from AMS series U502 (India and Pakistan). I have the 1955 sheet (also avail from Perry-Castaneda), and am hoping for a later edition. Note: The Worldcat entry [OCLC # 248723616] that says two US libraries have a '63 sheet is incorrect. Those two libraries have only the 1955 edition. Please let me know if you have a post-1955 sheet you can scan or take a few pix of. Contact me offline and I'll explain what I'm looking for. Thanks very much.
