Heavens, I don't know, Engine # falls in for a June'29, Engine number pad is not altered, but may not match frame number, thus the confusion. Motor may have been changed and NOT re-numbered. I will discover the body number and clear it up. "VERMIN" is NOT a special coupe, just a really decent regular coupe with like new interior, top, and rumble seat redone in 2002.----Bill W.
 
Just resurrecting this thread to add my photo for future ref. I just had my fuel tank acid dipped...

...and it revealed the number you can see below.

There was so much paint on it before that the number wasn't visible.
 
The stamper got the 8's upside down. Sometimes the entire number is upside down.
Now's a good time to weld all those extra holes shut.
 
Another thing you might check is the 8 or 10 rivets (or something) where the gas tank cowl welting is supposed to go. I don't believe they should be there. There is a wire inside the welting that goes over the tank for the hood to rest on that is tightened to hold it in place, not rivets.

I hope like heck that the fellow who acid dipped it for you nutrilized it to get all the acid out of the small crooks and crannys because if not...you will be very disapointed when you start seeing the acid oozzing from those areas after it is painted.

Don't ask me how I know!

Gents, this is a topic close to my heart - So I ask, at what point in manufacture was the tank stamped ? - I had read or heard that it was stamped after it was welded as a form of batch control for quality in case of leaks. This would have of course been some time before final assembly. Later it was stopped as an unnecessary step - is this true ?
Also this is particularly relevant to us in Australia because our open models and trucks were imported from Canada CKD so a tank date plus say 2-3 months would give approximate local build date. Thanks, Brian

atourer...

You are asking the 64 million dollar question! There are a lot of us out here that would like to know the EXACT reason why Ford stamped these tanks when they did...mainly from about May 1928 through September 1929.

All we can do is speculate the reason at this time and that was for quality control after the assembly of the tank itself. In other words after the tank was inspected...it was then stamped and sent to the various assembly plants throughout the USA.

The closer the assembly plant was to the tanks coming off the assembly line at Fordson/Dearborn, the closer to the build date in some but not all instances. As with engines, some sat around and were got to later thus making assembly further from the actual stamping of the tank.

If you go to my website and review the gastank articles and some of the data, you can see that there were at least three senarios of tank assembly to a car or truck body.

It is quite interesting.

Again...all we can do is speculate just what the reason was as to my knowledge, no one has really come up with the definitive answer as to just why the tanks were stamped in the first place. That answer is HOPEFULLY hidden in the Ford archives and HOPEFULLY some one will find the real answer.

Brian, you should check the article by Dave Slater [ Vic.] in Restorer July/Aug. 2010; ''My visit to The Australian Ford Archives".Australian production was not closely related to what went on in US. They actually were selling '28 '29's in 1931 & '32 along with the locally built 1930 types that went to 1932. Ian Irwin has also published about 3 very good books on Australian Model A's; ask some local Model A guys if they know of these.
 
Thanks, searched cowl but no luck. I was able to get assy plant # with battery acid method. My engine was built July 8th according to steves site. And speedo still has tamper tag on backside and shows w9, 1929 September. Right rear frame crossmember has pao stamped in it. Anyone have any idea what it is? Couldn't match it up with any Frame codes listed.


What is the "battery acid method" for revealing a deteriorated frame / cross-member number ?

Hi frank just noticed your question. Take a copper pot scrubber( I used one with plastic handle) and dip it in battery acid. Take a battery charger and hook negative side to peice that your trying to get numbers from & positive to your pot scrubber. Lightly run it across the peice. It's nasty so make sure & wear glasses, gloves & a mask & make sure and keep it wet with the acid or the arc can scorch it and make it hard to read. This method worked when nothing else would on my numbers. They were lightly stamped and deteriorated but it brought them out quite a bit.
 
Ok, bringing back a dead post or at least a post in a coma......here's mine it's on a '28 Tudor.

So what does it mean? 10-13-28 without the 28? since stamping was stopped by then in '29.
Funny thing is 10-13-28 was a Saturday.

I do not understand your question on this ; if it is a 1928, must be Oct. 13th 1928?
Re being a Saturday, I think you will find it would have been a normal work day, especially if in the morning. They had rotating shifts at the car plants. These days, we also have gone right back to working everyday & all night like before the 40 hour work week?
