hesham mentioned this Bo.1-to-Bo.19 sequence back in 2013. But, are we sure that these are designations for distinct aircraft designs? The Établissements Borel seems to have been lackadaisical about applying numerical designations. (OT: Later writers are also sloppy about attributing 'design' to Borel. Sure, Louis Borel was an aircraft designer but his brother, businessman Gabriel Borel was quite savvy about taking on outside designers.)

We see mentions of a 1911 Borel Bo.11 as a reconnaissance/trainer type. But contemporary references simply refer to this as a Borel Hydravion ... with BO 11 likely just being its construction number. In the case of the 1912 Borel Type Militaire single-seat tractor monoplane, the 'BO 9' construction number is clearly marked on the rudder.

For the most part, generic descriptions were applied instead - eg: Type Militaire regardless of whether it was yet another Morane-Borel monoplane or the 2-seat pusher recce type of 1912. Or designer names were used in combined forms - eg: Borel Ruby for the Frédéric Ruby-designed Torpille armed pusher, Borel Denhaut for the François Denhaut-designed Aéroyacht series, etc.

By the way,

the numbers of designation is not related to the years,and as I think the Bo.11 was just identification to the year
by this period,but the whole series maybe as following;

Bo.1 was a two-seat monoplane,called Borel-Morane,1910
Bo.2 was a looks like Bleriot-IX,1910
Bo.3 was a pusher biplane,1911
Bo.4 was two-seat military trainer float monoplane,1911
Bo.5 was a single seat military monoplane,1911
Bo.6 was a four-seat military monoplane,1911
Bo.7 was a two-seat trainer military monoplane,(Obus),1912
Bo.8 was a two-seat float monoplane,1912
Bo.9 was a two-seat monoplane with skids,1912
Bo.10 was a single-seat racer monoplane,called L'Obus,1912
Bo.11 was a two-seat trainer float monoplane for Navy,1913
Bo.12 was a single seat monoplane with skids,1913
Bo.13 was a military monoplane with a machine gun,called Borel-Ruby,1913
Bo.14 was a two-seat military monoplane with a machine gun and pusher engine,called Type Militaire,1913
Bo.15 was a racer flying boat,a monoplane like,with pusher 160 hp Gnome engine,called Monaco,1913
Bo.16 was a four-seat patrol and torpedo bomber seaplane,powered by two 220 hp HS V-8 engines,called Borel- Odier
Bo-T,1915
Bo.17 was a single seat fighter biplane, with machine guns,and called C.1,never completed,1918
Bo.18 was a three-seat twin float high-seas biplane Project,powered by three 400 hp Lorraine engines,1918
Bo.19 was a three-seat twin float biplane,based on Bo-T,powered by two 400 hp Liberty engines,never completed,1918
Bo.20 was a 10-seat twin float biplane,as a transport aircraft,developed from Bo-T,and called Bo-C,destroyed before
test in 1919

Hi,

there was also;

Aeroyacht I was a Borel-Denhaut flying boat biplane,powered by pusjer engine,1913
Aeroyacht II was the same as Aeroyacht I,but with cut-outs in the small low wings,1913
Aeroyacht III was developed from Aeroyavht I & II,but featured an even longer trailing rudder tip,longer lower wings, and conventional double-strut bracing-though still with wing-warping,1913
1921 was a single seat racer biplane
1922 was a triplane transport Project,need confirm
1923 was a flying boat high wing Project,powered by two engines
1924 was a three engined transport monoplane Project
Bomber was a twin engined bomber Project,need confirm or the year of the design ?
Borel-Boccaccio 3000 was a two-seat fighter biplane,developed from C.1,in C.2 category,1918
