I don't know for definite but I think that from 1812 to 1814 only grenadier and light companies in both line and light regiments would have wings.
In the images in the Historia Organica de la Infantería y Caballería Española by the Conde de Clonard the centre companies appear without wings.
In Los Uniformes del Estado Militar de 1815 by Antonio Manzano and Luis Gravalos the illustrations also depict the centre companies without wings.
The Osprey Spanish Army of the Napoleonic Wars 3 also depicts centre companies with no wings. It seems to be mostly based on the previous two books.
I haven't been able to find any direct documentary evidence ,however I did find some interesting Spanish sources on uniforms generally in this period which I've translated.
The first one also appears in the Osprey book.
From the Uniform Regulations of December 1811:
"For line troops. Short jacket without lapels, buttoned at the front, light blue baggy trousers, and half boots below the trousers,red cuffs, collar and lining with gold buttons and white waistcoat with sleeves.
The light troops wear their own uniform with the cuffs and collar of the same light blue color, white lining and buttons.
Both with a shako with a golden metal lion on the front for the riflemen, a grenade for the grenadiers and a white metal bugle for the light troops. Waxed canvas backpack and gray woolen cape."
The following text is from Asturian Uniforms from 1811 by José Luis Calvo. It shows the lack of uniforms and especially shoes that Spanish units suffered.
"Lastly, although scarce, unifroms were being received from Great Britain to equip the Galician and Asturian units. The 2nd of Asturias was provided with brown shoes and capes with which it was possible, in part, to alleviate the extreme lack of uniforms and in 1812 it received from the depot of La Coruña 800 jackets and as many colored cloth pants. Blue and gray shirts, shoes and coats, all of British origin.
While these things were happening with the uniforms of the regiments of the 6th Army (later 4th), the remaining Asturian corps that made up the 3rd division of the 4th Army (later 3rd) that operated in Andalusia, despite being close to British supply depots coming from Cadiz, there were few times when, unfortunately, they were equipped with the most elementary garments that could mitigate, in some cases, their nudity. The units that made up this division, which Ballesteros continued to command, were the veteran Line Infantry regiments of Castropol, Cangas de Tineo, Lena, Pravia, Infiesto, plus the Barbastro Light Infantry battalion.
On June 24, 1812, the Castropol Regiment received a new uniform in Algeciras, made in England, sky blue, with black cuffs, collar, lining and piping.
In the inspection review conducted by General Duque del Parque at the General Headquarters of Jaén on April 8, 1813 to the various units of the 3rd Army, the state of the clothing of the Castropol Regiment was as follows: missing 290 shakoes, 178 jackets, 187 pairs of trousers, 223 pairs of boots and 333 capes, this lack of garments was considered average.
The clothing of the Cangas de Tineo, Infiesto and Lena regiments was in the most deplorable state of use, for which reason those of Tineo and Infiesto were sent to Granada in order to equip themselves, while that of Lena, despite the degree of deterioration was maintained thanks to the efforts of all its men to keep it in use.
In the inspection reviews carried out in Tudela de Navarra on October 1 and 15, 1813, the Cangas de Tineo Regiment is found, although incomplete in minor garments (shirts and shoes), uniformed again; Infiesto has the entire companies of Cazadores and Grenadiers dressed, while the rest of the battalion, which is without clothing, has only received trousers; the clothing of the Castropol Regiment, received 16 months ago (in June 1812), is completely destroyed and the Lena Regiment goes to the city of Jaén to receive their clothing.
Likewise, in the previous inspections during the blockade of Pamplona, between November 1 and 23, 1813, the clothing of the Cangas de Tineo Regiment is in good condition; the one from Infiesto has just received a new uniform; the one from Castropol continues, after 17 months of use, with completely destroyed clothing, while the one from Lena has already received its in Jaén.
The different units continue to suffer from the lack of shirts and shoes. To partially alleviate the lack of footwear that the 3rd Army has, the Governor of the province of Aragón provided them with 1,555 pairs of espadrilles and 2,655 pairs of shoes.
In the inspections held in Borja on January 15 and 31, 1814, the Castropol Regiment continues with its clothing completely unchanged; the one from Infiesto now lacks some garments to be complete; those of Cangas de Tineo and Lena have their uniforms in very good condition, although the need for footwear is still enormous."
