Here is a mid to late 70’s Thermal teapot by Welware. Made of plastic these were designed to keep your tea hot and are ideal for campervan/camping. The design number on the base (980443) would date this to 1977.
Height – 16.5cm
Condition: The body has a few scuffs and marks but still looks fine. The small spout insert is missing (but this is fine to use without). See photos.
