Anyone have any idea of the rough age and what type of wood this sideboard might be?
Looks like oak to me.
in terms of age I’d pop an uneducated guess at 1930’s.
Are there any makers markings anywhere?
Possibly. It weighs quite a bit and has stuff on top of it. Can’t drag it out for a little while and was trying to work our roughly what I should charge for it. Have someone who wants it stripped and re-finished. Suppose I’m gonna have to drag it out to look for markings.
Does look like art deco era. The top looks stolid which is probably where a lot of the weight is but the drawers look like bookended veneer . Curved doors also look like bent laminations /veneer.
You have to be careful with veneers as aggressive sanding, particularly around the chipped edge of the door there could show through the substrate.
