Lamps that use a Tubular wick were at the upper end of the market and the wicks can be difficult to identify, if you have the old wick still in tube form squash it flat and measure the width in inches, not metric.
Don't have the old wick ! measure the outside diameter of the inner tube in the burner again in inches.
This Listing shows the Lamp Name with the wick in a drop down Menu
