We could REALLY use a picture for this article. --MKnight9989 12:40, 15 May 2007 (UTC)[reply]

I found a website, but I'm not sure how to upload files: http://www.landships.freeservers.com/new_pages/alby_155mm_gpf_kitreview.htm --MKnight9989 13:00, 15 May 2007 (UTC)[reply]

Japan should probably be included as one of the users of the 155mm GPF, because it used some GPFs that it had captured against American forces returning to the Philippines during World War II. Additionally, it is reported that Finland also used the GPF, and that Polish troops in Italy were other users of this artillery piece. — Preceding unsigned comment added by 119.93.54.202 (talk) 10:53, 10 August 2011 (UTC)[reply]

Should add Brazil and Chile to the users of the GPF/M1918 - the US sold M1918s to both countries in 1940 as coastal defence guns. There's a surviving M1918 at Fort Copacabana in Rio de Janiero. The Chilean guns were in service until the 1990s. The article really needs a lot more on the technical aspects of the GPF - the GPF gun was the first gun which could be considered the ancestor of modern artillery pieces. In particular the split trial, simplified barrel construction and two part cradle construction were all novel and influential in later artillery design.

Additional users added, also list of surviving guns, mostly from www.cdsg.org . RobDuch (talk) 02:39, 26 June 2016 (UTC)[reply]

Look for "The Reserve Officers' Training Corps (ROTC)" posted to Youtube by Motion Vault. There is footage of GPFs at 6:52 to 6:59, probably in a Latin American country. — Preceding unsigned comment added by 124.83.22.172 (talk) 11:34, 3 February 2016 (UTC)[reply]
