are the CBU-24s the type used on the -105 in the time frame of 1967
If you refer to SUU-30A/B, no. The clusters were the same but had a pointed nose. BTW, don't ask me why but if my memory's right, (not so good) similar SUU-30C/B were included in the Trumpeter A-10 kit! I choose the SUU-30B/B and H/B variants with the blunt nose as they were commonly used from the very end of the Sixties up to Desert Storm era. They either had horizontal or vertical winglets on fins. BTW, I've pictures of the B/B on F-105 in SEA. They were quite common on Korat Corsairs and were also a classical weapon on IAF Kurnass. So the scope of use was wider. CBU-24, CBU-52 and CBU-58 commonly used such containers.
Last, take care with the nose options. I put four ones: nose with or without cap, with fuse and with protected fuse. However, I used detailed pictures of a late CBU-58 fuse type as I never succeeded in finding good detailed pictures of the initial CBU fuses (they were different and some seem to be quite similar to the ones used on Mk80s series iron bombs). Accordingly, for an early bird (Vietnam/Kippur era), I would not use the bare fuse option.
