It was listed by Jeckyll & Co. Sold pieces stay on Sellingantiques as a record of what has passed through, and the next one is rarely far away.
Jeckyll & Co has dated this piece to the Victorian era.
I haven't seen this model before, perhaps it's quite rare.
This pair of andirons is stamped No.1, but not marked Carron, so I've included images of a related example, No.2, (not included in the sale) which is.

The crescent flowerhead appears on both examples in slightly different ways. The pierced crescent is also used (the other way around) in a stick stand produced by the Falkirk Foundry around the same period, Lorfords Antiques currently hold an example in their stock.
Well presented condition.
Happy to post, please let me know if you have any questions.
