I do not know the type of wood and I do not see a 'brand' / manufacturer on these.
The overall length is just under 10" and the platform (display area) is 9.25".
The overall width is 2.25" and the platform (display area) is 1.5".
The height is .75".
In case the 'scale' matters, these are part of an "HO" scale collection that I am selling.
Thank you for your interest.
