Not sure where this plane was made or much about it.  I have lots of images.  It looks like a small version of the Stanley No. 45.  The markings on it are:  45p.ook (or that is what it looks like to me) and a large B and the l/2 and the letters USSR.  The length is 5 3/8" across and the fence is 4 3/8" across and the blade is 1/4".  It has a depth stop.  It is in very nice condition.  Buyer to pay s/h calculated in USA.  Email with questions.
