As I haven't found any topic on the subject, allow me to start one (if ever this duplicates something, sorry!)
Instead of starting with the usual Beechcraft model number list (Models 16 to 101 in my notes) I thought it could be nice to deal with something a lot more unusual: an apparently out-of-sequence set of designations that end up making quite a coherent batch of missiles/drones in the 995 > 1100+ range.
995 probably the YBQM-126A prototype
997 BQM-126A, based on Model 1089
999E/H MQM-107B/-107C/-107D STREAKER

1025 MQM-61A CARDINAL
1025-TJ proposed turbojet version, also designated Model 1055
1055 Universal Drone System; medium high performance, subsonic, turbojet-powered derivative of MQM-39 and -61
?? SANDPIPER; AQM-37 modification with "hybrid" engines using solid fuel with storable nitric acid oxidizer (led to AQM-81A)
1069 high-altitude supersonic target (HAST) vehicle powered by Marquardt MA 206-XAA ramjet engine
1070 high-altitude supersonic target (HAST); tri-service target capable of flying at Mach 4 (XAQM-81A)

1101 AQM-37A JAYHAWK equipped with a two-stage parachute recovery system
1102 AQM-37A, non-recoverable, solid-state autopilot, improved wings for higher performance
?? CHALLENGER; AQM-37As modified with refined high-g autopilot, enlarged heat-resistant tail surfaces (USN); led to AQM-37C
1104 AQM-37C version for export
