The first LEGO Castle theme (Classic Castle) hit stores in 1978 and was sold until 1983. It included a humble six sets and was one of the first ‘themed’ LEGO lines. Later Castle themes introduced numerous warring factions and many fantasy elements.
These strapping men came in the 677/6077 Knights Procession set, the European version released 1978 and US version in 1981. The set included four of the black-leg knights (cas074) and two of the grey-leg knights (cas075). Whilst this set predates me by several years, I remember being very excited to discover these in a mixed bag of used LEGO at a fair that bought with my saved pocket-money when I was age 7 or 8!
CLASSIC KNIGHTS (CAS075 / CAS074)
The knight of the left (cas075) came with grey legs, red hips and torso, and dark-grey chin-strapped helmet. His counterpart came with black legs, red hips and torso, and light grey helmet with neck protector. Both figures shared the same smiley face and an identical blue, red and grey coat of arms.
These figures have very simple but effective designs. The helmets are surprisingly complex moulds including some fine bump detail on the right helmet. These guys are easily distinguishable as ‘knights’ and look right at home in a medieval LEGO world.
The dark-grey colour looks a little out-of-place on a light-grey figure but aside from that, nothing to fault given their age.
