Let’s not jump to conclusions here.
Cannot say this slot is 100% original from a single photo without closer examination; most slots found today have had something done to them in the past 75+ years.
Early Standard Chiefs would not have the TTT feature; TTT was introduced after the Standard Chief was already in service. I have a copy of the ad which Jennings used to introduce the TTT feature (on a Standard Chief); it shows the same marque and has a decal in the JP window but, unfortunately, the bars cannot be discerned; one would think the reel strips would conform to what’s on the decal.
By the time the Sun Chief came out, TTT had been out for some time and had become very popular; one would think TTT versions of the Sun Chief would be clearly identified, but that’s not always the case.
The Standard Chief had a long production run, most likely with variations; don’t assume the subject machine is an early one without knowing serial numbers.
I’d still go with my recommendations posted above without additional info:
What is the case serial number?
What is mech serial number?
Replacement reel strips?
Have the payouts been checked including TTT?
They are found with several variations.
Here’s one with an early serial number from an acknowledged expert who states these are original reel strips, award card and marque:
