Where it comes from
The apple is as old as the briar catalogue. French workshops in the Jura and English houses after them needed a bowl that filled the palm without the height of a billiard. They rounded it — a sphere, or near enough — and kept a straight shank. The name is literal. It is not a tomato (too flat) and not an acorn (the rim is not pinched). By the 1900s every factory list had an apple next to the billiard.
The specification
Bowl: spherical or slightly flattened sphere. Shank: usually straight and round; some apples take a light bend. Chamber: still a drilled cylinder, not a decorative well. Apple 423/24 is the measured piece: 130 mm long, 39 g, chamber 20 × 35 mm, bowl 44 mm high, 43 mm outside. That is a compact smoker. 487/26 and 488/26 are later rusticated sisters with a pierced heel — sculpture on the spur, same round bowl. 219/22 and 217/22 take bamboo shanks. We do not average those numbers across the family; only 423/24 carries a card.
How Levon uses it
The apple is a place he rusticates and carves. 487/26 is red, art-carved, gold on the stem, listed when eBay has the serial. 423/24 holds smooth panels against rusticated flanks. 217/22 puts three smooth belts around a rusticated bowl, then four nodes of cream bamboo. The silhouette stays an apple. The surface is the drawing.
