Help with diagram of UK 4,5 inch projectile

[trrrr]

Hello.
Somebody can help with diagramm and nomenclature of 114mm (4,5 inch) UK pre 2ww projectile filling with lyddite??
Projectile filling-black powder on top, then probably picric acide powder, then lyddite.
Projectile probably navy or coast artillery??

H'mm, my understanding is that 4.5 (actually 4.45 (113mm)) entered RN service in 1938 (and remains the RN's standard calibre), was used by Army AA in fixed positions in WW2 and also some AA/CA use. Lyddite doesn't seem very likely for this service entry date.

That leaves 4.5 Howitzer, entered service c. 1910 and remained in service to c. 1942, see https://en.wikipedia.org/wiki/QF_4.5-inch_howitzer

Be careful not to confuse the 4.5 inch Howitzer with the 4.5 inch AAA gun. Two totally different guns, projectiles, cases, etc.

4.5-in field gun was a 1930s design, most unlikely to have Lyddite filled shells. 4.5-in How (1910) would have had Lyddite fill for at least some ammo Mks.

Can some British Ordnance colector recognize, what exactly the name of that projectile???

Total lenght without fuze- 356mm,
lenght from base to rotating band 19mm,
lenght of rotating band 30mm.

From the shape I'd say 4.5in Howitzer, this shell weighed 35 lbs. The 4.5 HAA and 4.5 Gun shells were both about 55 lbs and a different shape.
