For helping keep this great
old truck web site
on the Internet for over 30 years! and not clogged down with Ads! Again, thanks! | | | | Joined: Feb 2016 Posts: 17 New Guy | | New Guy Joined: Feb 2016 Posts: 17 | This has probably been asked many times before but since I'm new on here, can someone tell me how to decode the last six numbers on my serial number plate reading 051990? These should show the production number of my truck but how do I read/interpret it? I understand the first four letters & numbers but am not certain about the last six numbers. Also, anyone know approximately how many '54 Chevy 3100s were manufactured in 1954? Thanks for your help. | | | | | Joined: May 2006 Posts: 8,351 'Bolter | | 'Bolter Joined: May 2006 Posts: 8,351 | That number would be sequential number from the plant the truck was built in, usually starting with 001001.
Bill Burmeister | | | | | Joined: Mar 2004 Posts: 256 'Bolter | | 'Bolter Joined: Mar 2004 Posts: 256 | DC: welcome to the site! Lots of great info out here. In the 1954 calendar year Chevy sold 325,515 trucks of all types. Of that number 170,842 below 5000# GVW were produced. Those last 6 digits are a production sequence number: there were 51,989 built before yours came off the assembly line for that model year. | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | As Bill posted:
51990-1000 = 50,990th truck off that plant's assembly line that year.
Flatblu4749,
That is interesting information regarding vehicles sold in the 1954 calendar year. I have seen GM documents for 1950, 1952, and 1953 (all truck models). Do you have a GM 1954 truck production report?
Thanks,

Seeing that you have your own 1954 AD site I could copy/send you the 3-4 pages dedicated to your year? | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | No thanks, I have seen it (I have it).
I like to find/use "primary"/original sources/documents, if they are available. | | | | | Joined: Mar 2004 Posts: 256 'Bolter | | 'Bolter Joined: Mar 2004 Posts: 256 | Tim, ok cool, I get it....best to not risk corrupting the General's actual numbers by using figures from a source that may possibly be incorrect. | | | | | Joined: Feb 2016 Posts: 17 New Guy | | New Guy Joined: Feb 2016 Posts: 17 | Thanks Flatblu. I was "assuming" that was the way to read it but wasn't sure. | | | | | Joined: Feb 2016 Posts: 17 New Guy | | New Guy Joined: Feb 2016 Posts: 17 | Tim--So was my production number 51,990 per Flatblu or 50,990 as you stated? I'm still a little confused. Why take a 1,000 off the number? Thanks DC | | | | | Joined: May 2001 Posts: 7,438 Extreme Gabster | | Extreme Gabster Joined: May 2001 Posts: 7,438 | Because the first truck off the line was numbered 1001. | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | Because the first truck off the line was numbered 1001. As shown in the Specifications Manual. | | | | | Joined: Mar 2004 Posts: 256 'Bolter | | 'Bolter Joined: Mar 2004 Posts: 256 | DC: I stand corrected....yours was #50,990 off the assembly line, the other guys are probably right. It may not make total sense, and I'm sure there is some logic to starting at 1001. Trust that you can get some good information from this site regardless. Welcome to the site.

Our is not to reason why . . . (of course we could speculate, but I will leave that for others - we will never know)
