I need help identifying a stanley plane I own.  It has the SW logo overlapping the bottom of the STANLEY logo, but only says Made in USA under it.  nothing else.  seems to be a mix of a few logo styles, but I have not seen this exact one anywhere else.  I have a solid brass adjuster wheel with no recess or writing.  the wood knob measures 1.25″ wide x 1.3/16″ tall.  the bed is smooth and measures 5.25″ long by 1.50″  wide.  There are no markings, dates, #’s etc… anywhere else on plane besides the logo. There is only a raised post under wood knob for stud, no raised ring in casting.  There is no lateral lever on frog, and held down with round head screws.  Is this a mix of parts? what years and type is it?
