Was wondering how I could find a Military Pension Record

[Colin Goodheart]

Hello! I just found this article dated October 15th, 1841 in the "Post- Och Inrikes Tidningar". It mentions my 5th Great-Grandfather Fältväbel J. G. Ljungström regarding a pension. I assume the pension is for his military service since the article mentions his regiment and rank. Do any of you know how I could find his pension record?
