Left to right - but not in chronological order:
Uniphot - large/small knobs on raise/pan handles; phillips screws on tilts; unknown if black paint finish was the only choice. Sticky label. Thanks for loan of sample to Bernie Lehmann
Leitz - large/small knobs on raise/pan handles-this two size knob seems the innovation of Leitz, hex bolts on tilts; black paint finish believed to be only choice; Marchioni-type metal label.
KingHome - current version by Oliver Yang. Large knobs only on raise/pan; black and silver anodized finish available; allen bolts on tilts; sticky label on apex and on removable leg. The 1/4-20 tripod mount at the bottom of the column seems the innovation of KingHome.
StarD - believed to be a copy by the still existing Davidson Optronics company in southern California, production concurrent with the Marchioni Tiltall (see earlier blog) and ended with Leitz purchase. Knobs for raise/pan seem to exist in both a plastic and an all metal version; unknown if the tilt handles (as shown) were only available in silver of if painted black was only finish choice; sticky label.
Marchioni - the original. small/small knobs on raise/pan; phillips screws on the tilts; silver finish believed to be the only choice; very nice metal label.
