Rifles like this were quite common in the partisan warfare during and after World War II. Yes, it may be bubba'd, but it may also be a piece of history.
The Latvian Museum of Occupation has a similarly cut down Ross MKIII rifle (Ross rifles were sent to Latvia in 1919) that was modified as a partisan weapon after World War II when many Latvians, Estonians, and Lithuanians chose to struggle agaisnt their communist oppressors by taking to the woods and fighting a geurilla war.
The Latvian Museum of Occupation, however, calls it a "Ross-Enfield."
