Need Help With Swedish Stamp And Postmark

I need help.This is a Swedish postcard. I think the 15o is a Scott number 168 and if I read the catalogue correctly, it was released in 1928. My best guess is that the 10o is a Scott number 128 with a release date of 1925. The center line of the CDS reads 18 1. 32. 12 13. I interpret this as meaning 18 = Military time (6 pm), 1 = January, 32 = 1932, 12 and 13 are facility codes. I know less than nothing about Swedish stamps and their postal system. I have a handful of Swedish postcards and this is my first attempt to learn about them. Any help will be appreciated.

18th of January 1932, between 12:00 and 13:00 hours.
