It should be an August of 28. Is this the block number?
For that month,...the hood, radiator shell, front brake actuators
and the front fenders aren't correct......do you have more photos?
The headlamp lenses are for the TWOLITE system, which came out in February 1929, and the horn is a JC Whitney aftermarket, just like the one that someone put on my 29 Tudor. All 28's had fluted lenses.
