The bricklayer letter's comic weight was fixed between galleys and hardcover: galley *320 kg* became "75 kg" (p. 139).

This is a revision: the same material was reworked in substance between draft and print.

In the galley proofs. The 1995 galley proofs: I weigh 320 kg in block #11 of the accident form.

In the published book. Scene 43 (pp. 138–140)

Evidence. A single source reports this.

Further notes. Galley 320 kg (~700 lb) broke the barrel-counterweight joke's arithmetic; the fix restores it. DECODE HISTORY: this is the entry whose direction the source-note drafter reversed; folded with the corrected direction. Cross-ref diff-bricklayer: the scene itself is post-1993 material, so its text saw both a late addition (1994) and a final-stage numeric fix (1995–96).
