I think that "Four Sir" was the model line that SR introduced to replace their "Royal" parts, in the early 1980's. The Four'Sir seatposts are arguably better than Campagnolo Super Record posts, as they are lighter (< 220 gm) and they don't slip AT ALL. They are nicely fluted and beautifully anodized. If the black plastic bands are removed they are hard to tell from Campagnolo SR. Baron Corpuz offered these stems for years at a bargain price. Here is a picture:
There were also Four'Sir stems with black circular labels, but I don't think that Four'Sir cranks or pedals or handlebars were ever introduced.
SR Four'Sir replaced SR Royal SL parts which competed with Campagnolo Super Record.
The ultimate parts from SR were SR Royal Extra Super Light (ESL) parts which had no equal, they were one notch above Campagnolo Super Record. They were marked by chromed world class circular bands taped around each part (stems, seatposts, crank arms.) They came with all-titanium hardware (the drilled-out stems weigh only 210 grams, the cranksets had SR-logo titanium chainring bolts and plastic caps and titanium crankset spindles and alloy cups.)
The chainring pattern for SR Royal ESL looks like super record, but the rings were lightened so that there were scallops or flares near the chainring bolts (if you think about cutting out the inner spider with a cut that goes not towards the spindle but towards the adjacent spider tang, you can figure out the look.)
