I believe this silver trivet was owned by Jane Waller. It is now held by Jenn Waller Mottram. The trivet slides in to form a circle, and out to hold a larger pot. The silver is worn off in several areas.
The underside of the trivet has four wheels. There are markings that display the number 3 on both sides. It also says WOLFF overlaid with a large W.
I think the engraved flowers on this expandable trivet are primroses.
I can’t find any record of a Wolff company. If you google for Wallace silver plate expandable trivet you can find very similar items.
