愷 / 愷長 · mark readings
Read the lid and base separately: the catalogue assigns 恺 to the lid and 恺长 to the base of this bamboo-drum pot.

Start with the reading
愷 / 愷長
The one-character impression and the two-character impression are shown separately. 恺 / 恺长 follows the catalogue’s simplified transcription; 愷 / 愷長 gives the traditional search forms. The slash separates two marks, not one combined seal.
A documented vessel
Xu Sihai’s 双线竹鼓壶 on printed p. 154 is 10 cm high and 19 cm wide. Its caption identifies the lid and base marks; the detached close-ups do not establish which face of the lid carries the impression.
How far the evidence goes
This is a different pot from the identically titled example on p. 42 (PDF 68), which carries 生义 / 万贡珍印. A repeated shape name does not make them one object. These readings establish the documented pairing, without identifying a full personal name or each person’s workshop role.
