Visual Difference between stock and gel seat?

[stinger]

I bought my bike used and honestly don't know whether I have a stock or gel seat on it. Is there a visual way to tell? It's very squishy and not too uncomfortable but I'm considering sending it off to Sargent to get them to do their thing with my seat pan

One of the differences that stands out is the stitching. The stock seat is stitchless while the gel seat has some stitching between the panels. Another thing is the little tag that says 'Triumph' which is sewn into one of the seams...
