Hydrochloric acid works wonders on 1929/30 FEDCO plaques

Recommended Posts

I have finally tested the use of paint remover and acid to clear paint and rust from an unreadable FEDCO plate. Unlike the versions preceding a Series 65/75, these are commonly very difficult to read without guesswork as the letters are entangled in the general pattern of the FEDCO plate. Here is the plate before starting, only the top two letters are visible, and second image while the paint remover is doing its job.

The I used 4 + 4 minutes of 30% hydrochloric acid for the third picture with much improvement. And finally 10+10 minutes including using a fine combed wire brush in between. Finally water cleansing to get rid of the acid, and now all letters of LS831E are clearly visible.

To finish off I added some black paint and wiped off the paint from high points. Now even the FEDCO name at the bottom can be read. Then I did the same with the badge from another of the 71 Tourings made, and found it to be #LS831S = 768316, two digits away and another of the 11 cars made in July 1928. Guess they all were shipped to Norway?

Well done, that is a remarkable difference.

That looks to be #LS831E to me.

Apologies, the main subject FECO badge is LS831E, the second one on a grey panel is LS831S. I did write up the numbers in an earlier version, but the AACA option of "insert a picture randomly into your text and delete everything when you try to correct it" made me do everything 3 times and in the final version the letters were forgotten.

Amazing that you have two FedCo tags that are only two cars apart in the sequence. For what it is worth:

Serial Number LS-831-E
Found in range LS-400-P to LD-999-D
Serial 4318 of 35999
Year 1928
Make Chrysler
Model Name 65
Model Code P
Plant Detroit
Engine 6 cylinder 195.6 cu.in. L-head
Wheelbase 112 3/4 inches
FedCo Number LS-831-E

 

And:

Serial Number LS-831-S
Found in range LS-400-P to LD-999-D
Serial 4316 of 35999
Year 1928
Make Chrysler
Model Name 65
Model Code P
Plant Detroit
Engine 6 cylinder 195.6 cu.in. L-head
Wheelbase 112 3/4 inches
FedCo Number LS-831-S

 

Both from my Chrysler FedCo/Serial Number/VIN lookup tool at https://www.ply33.com/Misc/vin

That is a neat tool, I tried it with the FEDCO of my Canada made Series 65 and it worked superbly.

If you get a new toy is often difficult to stop playing with it.

My Series 65 engine had its casting/parts number (40629-4) fairly visible in the accumulated 90 years of rust and dirt, but unlike my newer Series 65 engines there was no evidence of a casting date. That is until I applied acid and wirebrush scrubbing around the casting number. Now it has become an engine just made before Christmas 1928 and as a bonus the name Hercules appeared below the casting #.

Anyone know more about this, was Hercules an outside engine block supplier? Car is Canadian by the way.

 

I also applied acid to the engine number which now stands out almost as it was made yesterday.
