It's definitely an SHS model, as it has the SR Silver crankset with the large chainring swaged to the crankarm. The SHT used the upscale SR Royal-5 with an integral spider and removable large chainring. The SHS was 3rd in Sekine's hierarchy at the time and was considered lower mid-range.
A few words of caution about the SR Silver, as it uses an atypical 3 degree taper, making replacement spindles harder to find. Also, with the SR Silver, Sekine generally used BB shells that were closer to 70mm than 68mm, making many owners think they need a spindle with the wider spaced bearing races found on spindles for a 70mm BB shell. However, the cups used by Sekine with the SR Silver had very thick faces and they used the narrower bearing race spacing found on spindles for 68mm BB shells. With all these deviations from convention they were at least standard English threading.
