The WALITY 69TS is the smaller version of the 69TL. Just like the 58C being a "mini me " version of the 71J. However the 69TS has some differences. Firstly, it has a single start cap thread as compared to the 4 starts of the 69TL. Secondly, the barrel and cap have the same diameter so there is a small step up at the end of the cap threads on the barrel. The stock GP fine nib a no 5.5 Indian: As I love to experiment, one of the following pens is upgraded with the Schmidt system FH341. L-R: Schmidt FH31, Stock, Schmidt FH341 The 69TL with the TS: Some experiments with third party nib systems on the 69TL, stock is a no 8 Indian. L-R: Schmidt FH31, Pelikan M200, Stock, Bock-Conklin no 6 set v deep, Schmidt FH341 Finally a size comparison: Lamy 2000, TL, TS, Pelikan M200. Even though the 69TS is not as popular or as well known as the 69TL, I really like these pens. Ideal for tucking into small pockets or to give to your child ( with a good smooth nib). Cheers, Hari
