The Rimcollian was started sometime in 1950s, continued for some years with specific periodicity and folded up in 1970s. It was revived in 1994 with an eye for bringing Rimcollians together in large numbers during the 1997 Platinum Jubilee celebration. Lt Col (retd) Jasbir Khurana as editor and Sidharth Mishra as assistant editor were instrumental in its revival. In 1998, the functioning of the newsletter was formalized and decided that its circulation be encouraged among those who donate to the ROBA Trust, which was to set aside Rs 100 per donor per year to meet expenses. Col Khurana retired in 1998, and Sidharth Mishra took over the editorship. Soon after ROBA Trust given shortage of funds stopped paying for the printing and to stop the newsletter from folding up, push was given to raise money through advertisements etc.

​

In 2012, Sidharth Mishra gave editorship in favour of Brig CS Thapa. A statement on income-expenditure during 1998-2013 showed that the newsletter never bled the ROBA coffers and always maintained above breakeven status. In 2013 the newsletter did not have a print edition, which was resented by several Rimcollians and thus it was revived in the present form in 2014 with Brig Thapa as Editor and Sidharth Mishra as Publisher (Under the RNI rules.).

​

While reviving the print edition in 2014, then treasurer Maj MS Bedi created a separate Magazine Fund so that the newsletter has a dedicated corpus. He also started a lifetime subscription drive, promising two print edition each year to those who paid Rs 2000/- magazine fund. Maj Bedi and Sidharth Mishra as a team also undertook a massive fund-raising drive bringing big monies in form of advertisements in the glossy magazine. Today there is approximately Rs 50 lakh in the magazine fund and over 600 lifetime subscribers. Such professional marketing could be done as with a foresight The Rimcollian title was registered with the Registrar of Newspapers in India (RNI), giving legal sanctity and credibility to its status.

​

In 2018, Brig CS Thapa all of a sudden passed away. At this point, former ROBA president Air Marshal PP Reddy became the Editor. Under his leadership an Editorial Committee was created of five more members to take on the onerous tasks of various publications for the centenary like centenary issue of the The Rimcollian, calendars, Centenary History, which went a long way in generating espirit-de-camaraderie in the community’ It may be noted that all these projects were self-funded and generated profit adding to the corpus.
