The match Suriname vs British Guyana 3-0 was played in Cayenne (not Paramaribo), but not 1 October but 30 September.
The Surinam team at first would leave for Cayenne 18 September, but British Guiana reported to the Surinam FA they only could play 25 September earliest. Suriname now left 22 September. In that newspaper report it is mentioned these are the first matches for the Caribbean championship (

I could not find anything about the match 28 September vs French Guiana (L 2-3). In the report of the first match it is mentioned the next match was 30 September (which must have been vs British Guiana) and the last match 3 October (no opponent mentioned) (

After protest of Suriname, the proposal of Martinique was accepted to replay all matches, but due to lack of time this wasn't possible. One match was played but the gold and silver medals were handed out to the managers of the foreign teams before that match (report doesn't say to whom exactly) (
