That sale was only the last link in a chain,
the lens pops with a "fresh to the market" photographer set...

God, what have bad memory!
Reviewing the information, I realized that I have in my collection, 3 more examples of Lerebours & Secretan Petzval lenses without serial number!
Two of them comes from the same photographer set that I post before. Pretty sure that the 4 lenses were a whole set of a daguerreotypist. Camera with big lens(maybe A. Millet) was added later.
3 more Lerebours & Secretan Petzval lenses without serial number.
The small one...from the daguerreotypist set.

The big one...from the daguerreotypist set too.

Hi everybody, I have very first Petzval made for A Gaudin by Lerebours. One mark "5" on the body, near rack and pinion, so It's the serial of this lens? Thanks!

Re: Lerebours Serial Number - Rice Writing
It is not the serial number. Normally, these small numbers identify some, or each lens part.

Hi anachromatic, Are you sure? Check the link below out. The number on that lens (same brand) is 4186 - too big number to identify any lens part.

I have also few lenses with 4 digits stamped in and those I consider serial numbers.
Soooo, it all depends on the situation.

Re: Lerebours Serial Number - Rice Writing
Just confirming that the lens Steven is talking about is also the lens I bought, so serial 2964.
The brass is indeed non-Lerebours. I have other lenses to compare with.
Few months ago I picked up a Lerebours & Secretan landscape lens with missing glass.
What appears to be the rear cell holder is different as it doesn't have any thread in it. Internal diameter is 85.5mm and it appears that's a receiver for a lens cell of some sorts.
So yes, I'll be milling that non-Lerebours brass down to fit the 85.5mm landscape lens receiver and assemble as such a functional landscape lens albeit with a different serial number on the glass (2964) as the barrel (4914) or 1950 units apart ;)
As for the landscape barrel, came with two washer stops, brass lens cap is missing and a few screws holding the pinion.
I'm clearly not a purist !

I have come to the conclusion that edge serial number scratching is not a "prevention of fraud", but more a method of keeping tabs of the glass he ( Lerebours OR Lerebours et Secretan) provided for (probably UK based) makers who made the brasswork.
Note that these 2000 serial numbers are around 1845/6.
Remember that the achromats used in landscape lenses and the front cell in Petzvals were identica. 81mm was a popular size for Lerebours and most serial numbers in the 2000's are Landscapes - so perhaps the achromat was used in a UK landscape lens around 1846?

Age looks to be around the 1850's.
