I understand your point. I agree, that 1995 or 1996 for a withdrawal date isn't much difference indeed, but in this case it is sure, that all units, that used Topas were disbanded in 1995 or before.
By "vague sources" I meant in this case article in Polish Wikipedia with a statement, that the 7th Coastal Defence Brigade was disbanded in 1995 due to reaching exploitation limits of Topas and PT-76. It would suggest, that they were used until the brigade's end; unfortunately, with no reference to support it. According to other articles, in 1994 there were disbanded most (if not all) brigade's battalions.
