Those 3/4 size Spoilers are sweet!
The serial number should be stamped into the fretboard, just beneath the 24th fret. The 1695 number from the pickup cavity is not the serial number.
It could very well be a 30.75 short scale, the top frets look closer together than on my 32 Spoiler. Best way to measure is from the inside of the top nut to the middle of the 12th fret, and then double. 30.75 is 78,1 cm, 32 is 81,3 cm.
