No real clue but looks to be very old for a BMX the loop tail and odd construction would indicate a lesser builder from the late 70's early 80's most likely California. There where literaly 100+ lesser US frame builders thoughout the BMX boom that built frames finding info is nearly impossible. Yet this one has enough uniqeu it may still be ID by some one.
