NIGP 16040: Knockers and Stunners

I cannot write the summary as requested. The source provided contains only the NIGP code number (16040), its name ("Knockers And Stunners"), and no substantive information about the code's scope, recent solicitations, issuing bodies, geographic activity, or dollar values.

To produce a usable summary for business development professionals, I need the <most-recent-state-local-contract-opportunities> block referenced in the task instructions. That block should contain actual state and local solicitations — issuing body names, notice types, response dates, and scope descriptions — that ground the summary in real procurement activity.

Without recent opportunities data, I cannot credibly characterize what state and local governments actually buy under this code, which jurisdictions are soliciting, where the activity is concentrated, or whether the code warrants pursuit right now. To proceed, please provide the recent-opportunities block.
