Have two of the 1x4x5 frames for door part 4131 that do not seem to be identified
in BL.
Came in a large lot of loose (LEGO) parts.
Material, color and design seem consistent with LEGO.
But no LEGO logo or part number present.
Also, base has no understuds.
Please see attached photos (including a 4130+4131 2x4x5 complete door for comparison).
Does anyone know this (unidentified?) part?
