Hi

The Engine of my 1929 TudorSedan doesnt show
a engine-nr :mad:

I should be able to read original nr
on the frame near to pedals/coal ? :confused:

Frame-Section is covered by fiber-ribbon (and body).
Any idea how to find Nr without taking body off?

Thank you

Dear Christoph,

Based on my extensive experience (1 car) - I pored over my chassis frame when I had the Roadster in bits. I very carefully wire - brushed and checked over and over. I just couldn't find a number. The chassis frame wasn't badly rusted, in fact quite clean, but I assume surface corrosion had worn away a 'shallow' punched number. I can't remember my reference source, but the frame number is on the left side, in the area below where the front door is hinged. Other posters may be more precise.

You do know there should be a date stamp on the engine side of the firewall on the driver's side (left hand drive). This stamp is sometimes upside down (mine is), faint and may be painted over.

Sometime during late 1928, the serial number was discontinued to be stamped on the frame. This is particularly true to the Model A's built in Canada for export to other countries, before plants could be built in those repective countries.
 
Thank you

I found a pic (where the nr should be) on an other HP.
But even i could be sure to find a nr on the frame:
I will not lift the body ;-))

Will try to have another look onto the engine
(under the paint)

Thank you

The number on the engine should be easy to find and read. It's just above the water inlet, and should be stamped into the original rough cast iron. If it's stamped into a smooth surface then the original number was ground off or machined off and a new number stamped.
 
Acid etch process to reveal ground off VIN's

For an engine that has had the serial number ground off or restamped, has anyone ever tried to reveal the original number using an acid etching process?

I would think that it might work using the same principal as Nic-A-Date that brings out worn off dates on worn nickels ( http://www.wizardcoinsupply.com/product/nic-a-date.html ).

There is an interesting article about this process of "Restoring Altered VIN's" in Evidence Technology Magazine: http://www.evidencemagazine.com/index.php?option=com_content&task=view&id=366&Itemid=9

The article explains the process:

"When a number is stamped into a metal object, the metal underneath the number is compressed and hardened. Even when the number is ground off, this hardened area may still be present. By applying an acid solution, the metal can be slowly eaten away and the number may reappear. This is commonly referred to as “raising the serial number”."

....any forensic Model A experts who have tried this process?

Fordially,

Hi Tom
Ja - Thank you - I know
Sadly there is no Nr (no old one, no new one, just nothing)
Maybe (some ruins) under the paint.
I will have a look.

Hi Brad
Long time no mail ;-)
Ja nice idea, I heard of that too.

Hi all
Please answer to Brad`s question:
....any forensic Model A experts who have tried this process?
