Looks like a '34 Master. Master is narrower and longer than the '34 '35 standard. The '33 does not have a removable trim ring.
Not a 35 master. Fill on 35 master is behind shell. No hole in top of shell. Posted using the Full Custom H.A.M.B. App!
Just measured my '34 Master. The grill insert area should measure 31 1/2 inches top to bottom. Standard is shorter.
