did some research for ya mate.
That 30pict-2 carby is from 1968-69 vws (the 1500 series beetles :P, but regardless, there were still 1600's during this time too in the type 3's etc. but they would have been the twin carb. Low light bays would have been a single port 1600! And as to whether the 1600 sp kombi used that carby i really don't know to be honest. But it suits the time frame of the 1600 sp kombi in 68-69, and the sp kombi was single carb.)

Mind you though, it doesn't say the engine is that.
Heres some differences from my workshop manual (1100cc to 1500cc)
They are a bit more technical, but will lead to determination i guess (maybe...??)
1200:
Comp ratio 6.6:1
Ignition firing point: 5 degrees BTDC (where dissy rotor is pointing to cyl. #1 in cap)
bore: 3.031''
stroke: 2.520''
Valve Stem diameter: (inlet) 0.274''
Valve stem timiing (inlet opens): 2.5 degrees BTDC
1500:
Comp ratio: 7.5:1
Ignition firing point: 7.5 degrees BTDC
Bore: 3.27''
Stroke: 2.72''
Valve stem diameter: (inlet) 0.3128''
Valve stem timiing (inlet opens): 7.5 degrees BTDC
I spose the best way to determine is know on the crank pulley where 0 to 15 degrees is... and the best bet would be to unclip the rocker cover and take a look at the valve timing to determine 1200 or 1500, because they have the most notable differences.
Even the stem diameter, if applicable to measure if you can somehow get a vernier caliper in there, would determine 1200 or 1500.
Saves full tear down then
