We started to use silenced systems to reduce the decibels around the 1974 to 1977 era as did many of the Special Saloons and Modsports. It was quite loose on the regs, but some of the National boys were looking ahead and not taking any risks with strict MSA scrutineers.
This Hart Escort was barn found with a full system on it, so the last time it raced was in 1979, driven by Andrew Grover, proving the system was pre 1979/80.
If there are images of the Hart Escort when raced with Geoff Woods, Phil Winter and Andrew Grover, you could identify a time bracket. I do know that the early days of this Hart Escort had the header coming out of the top of the n/s wing, it was very loud, hot and prone to flaming the hair of kiddies heads.
