Wanted - Early Northern Tasmanian Cave Postcards

[jellybean]

I am interested in early postcards of northern Tasmanian caves including: the Mole Creek Caves (Scotts, Baldocks, King Solomon) and Gunns Plains or Ulverstone Caves.

Spurling cards not required have the following numbers: 139, 400, 401, 402, 403, 405, 407, 408, 409, 411, 412, 413, 415, 417, 419, 420, 421, 422, 423, 424, 425, 431, 443, 465, 466, 467

I understand there are 24 numbered Spurling cards of King Solomons Caves and 14 of Scotts Caves. Would love to know what else exists, especially of the Gunns Plains area.

Any information also gratefully received.
