Before they produced these in clear acrylic blocks, Hama made this model 5410 level in an aluminum block.  This Vintage item is probably from the 1970's.  It features, of course, a bubble level and two feet to facilitate changing the orientation of the level.  It fits any standard camera/flash shoe and also has a female 1/4"-20 thread for mounting on a tripod or light stand.  It is a New Old Stock item in the original box.  We all want to be on the level but this one does it in style.  Ships via USPS Ground Advantage.
