This cover was the same basic design and used the same pressed plate construction as the longer, taller (but slightly narrower) EB/Les Paul/Ripper/Thunderbird cover. It was first fitted to the SB300/400 in 1971 (but not the SB350/450) and later to the Grabber and G3. These were all models with budget bridge units; this cover will not work with the standard two point and three point bridges most widely fitted to Gibson bass guitars at this time.
Just like the aforementioned larger cover, it was manufactured from pressed brass, but nickel-plated rather than chromed (actually a very few of the very earliest larger covers were also nickel-plated, those fitted to the first Thunderbirds, but these are very much the exception). Covers fitted to SB basses were typically etched with a pre-war style scripted Gibson logo, as seen below, and oriented the opposite way to the norm. Some very early examples of the Grabber also had a logo'd cover - see this early Grabber advertisement for example - but using a more standard early seventies Gibson logo. However, the overwhelming majority of Grabber/G3 basses were shipped with a plain cover.
