Hi Delia
The sideboard is made by Jentique. The furniture is one piece ie it doesn't lift off a base; I have attached a few photos of the underside but they didn't come out as well as I'd hoped so let me know if you need more. I also attached a photo of the feet; all four are intact. I haven't polished the piece yet (which I will do before sale, of course)... it really is in immaculate condition with no scratches other than ones shown in the photograph.
I look forward to hearing your feedback,
Julia

Thanks, Julia,
Rather than polish this, simply wipe it free of any dust with a dry (or only slightly damp) cloth; some buyers appreciate the unpolished look.
Based on the photographs and information provided, and subject to examination, this is:

Hi Delia
Thank you for your valuation and your advice on polishing. Do you have any suggestions as to what channel(s) I should use to market / sell it to maximise its value? i.e. the best auction houses or websites to use. And any suggestions as to the reserve price / strategy?
Regards
Julia
