B-25 Construction Numbers - Need Your Help

[mrhenniger]

I have recently been data mining the web, books and magazines for the histories of various surviving B-25s. One important source of information is Joe Baughers serial numbers lists which can be searched using this search engine...

I recently got my hands on a copy of "US Military Aircraft Designations and Serials Since 1909" compiled by John M. Andrade. This book is also an excellant source of information for serial number tie-ups and model designations etc.

The problem is that Joe Baugher's lists and Mr. Anndrade's list sometimes don't match for s/n and c/n tie-ups. Joe mentioned that is lists are from "Lloyd's B-25 book".

So I am asking for your assisting. If you have access to a B-25 could you please take a look at the data plate for me and write down the USAAF s/n and North American's c/n? I am hoping this will point towards which set of lists are correct, but I suspect Joe's lists are correct in this case.

Mike,

More than 10 years ago now, I ran into this same dilema while researching the history of the Yankee Air Force's B-25D-35-NC 43-3634. The data plate in the aircraft shows it as "B-25D-30-NA 43-3634 c/n 100-23960. Andrade's book has 43-3634 as c/n 100-23460, a difference of 500. I believe this book has numerous errors in it when it comes to B-25 c/ns.

I created a two page spread sheet that compares the B-25 Construction Numbers by Model/Block Number from three different sources: Norm Avery's book, John Andrade's book and an article on civil B-25s by William Larkins that appeared in the Spring 1978 issue of the American Aviation Historical Society Journal. I will scan this document and email it to you in the next couple of days.

Good luck!

Thanks a bunch Todd. It is nice to know it is not just me!

Thanks Todd! If it is any easier, feel free to just email the spreadsheet to me. Is it an Excel spreadsheet?

BTW... I go on vacation at the end of the week for two weeks, and I want to try an keep my Hotmail account as clear as possible. If you get a chance could you send it by Friday morning at the latest?

Thanks again.

Hi All

Where on the B 25 would I find the aircraft data plate?
