The tag tells everything. Maybe we can figure out what it is with more information. Get the casting numbers off of the maincase and tailhousing, see if the input is 1 1/16" or 1 3/8", see if the output is 28 or 31 spline, if it has a 1 1/16" input shaft remove the lid and count the teeth on second gear . Also measure the tip of the input shaft to see if it is 1 1/8" or 3/4" long. Tell what you find and I'll tell you what you have.
