Mystery Spad?

[Stig Jarlevik]

Well Clint

Without knowing in detail how neither the French production nor application of the SFA numbers worked, the below is built on guesswork, but here we go.

Initially the SPAD was not a very successful company.
Not until the very useful S.VII/XIII and other types based on that came along did they reach maturedom.

I can well imagine SFA assigning s/n 1-999 to SPAD
Then giving 1000 and up to someone else, 2000 to a third company etc. No idea how big these assigned batches were. Possibly in my books/articles somewhere.
We can be very certain though that no way almost 19000 SPAD aircraft were built furing the war!

Possibly the batches were allocated by SFA to factories, meaning that if SPAD built aircraft in more than one factory, such a place may have been given its own batch number

As you can see from the Denis site S.904 is in a sort of "limbo" all by itself

Hello Stig,


I haven't been looking at French serials for long, but the numbers it seems to me were specific to the manufacturers. I haven't checked on Albindenis before writing this and of course though the serials there are very useful they are very incomplete.


What I'm saying is Spad had a S.901, but Breguet had a Br.901 and Nieuport a N.901 and so forth.


The numbers we're seeing are not SFA assigned IMHO.

Aha Clint

I think you confuse Italian serialnumbers with French

SFA gave every manufacturer the same ranges.
You will have plenty of duplicated numbers, differing in their letter code only.

Stig,


Yes thats what I said.The second sentence of my post. I agree the first sentence was not that clear.However, when you write :


can well imagine SFA assigning s/n 1-999 to SPAD
Then giving 1000 and up to someone else, 2000 to a third company etc.



Thats what I responded to and if you read that I believe you'll agree that it could be read to suggest the opposite of your last post.


I'm suggesting the polar opposite of the italian system, but I hope you can see what I , somewhat surprised I must admit, thought you were saying.

Ah yes, sorry

Was in a too much hurry...
But I still do believe SFA assigned the numbers, not the manufacturers themselves.

Cheers

Hi Stig,


Very possible. Did aircraft that were not accepted by the military receive a number on the tail?. If not that suggests S.901 was more than a prototype. Did for example unsuccsessful prototypes built by Spad receive a S. number at all?

Very good question

I know far too little about the assigning of serialnumbers by SFA and their relationship to the numbers the manufacturer used.

The French manufacturers were very early to adopt their specific numbers, so if you check those known, you will find they usually began from number 1.
If they actually put a plate on the aircraft is not known by me, but Breguet at least painted the factory number on his aircraft, in many cases on one of the struts.

Caudron kept a very good diary which seems to have been preserved. Their c/n are very much different from the SFA assigned numbers
