Gitzo R. No.4 head brand_Calumet though collectors take note: theThe Gitzo R. No. 4 head is an old school all metal tripod head with three way adjustment. The very large camera mounting platform (about 10x17cm) makes this head well suited to use with large format cameras that need a bit of extra base support. Standard 1 4 thread for camera mounting, 3 8 thread for tripod mounting. In good cosmetic condition, with some surface wear from use.
