Even with its troublesome and delayed development, once equipped with the more powerful R-25600 Twin Cyclone 1900hp engine and the original 3 bladed prop replaced with a four, the Helldiver became a formidable asset to the US fleet in the Pacific.
As a dive bomber, the Helldiver proved to be highly successful - enabling the two seater aircraft to deliver its payload with pinpoint accuracy and its operational range was far beyond that of the single seat fighters - a critical requirement for any carrier-launched attack aircraft.
The Helldiver's RPM in 100’s is indicated on the outer scale, whilst RPM in 1000’s is indicated in the inner window at 9 o'clock. As the engine speed increased, the large pointer rotated clockwise.
Passing the 12 o'clock position, the numbers in the small window would rotate and indicate the RPM in 1000's. This is a ‘sensitive’ tachometer in that it provides more precise resolution of the engine speed vs earler versions with a single pointer and an additional internal speed ring for the full RPM range.
With a service tag dated 3/8/47 this generation of of tachometers went onto to be installed in the carrier-launched USN Douglas Skyraider which eventually replaced the Helldiver in the postwar years immediately follwing the end of hostilities.
With its highly detailed 1/72 or super detailed 1/48 scale model of the Helldiver mounted above on its magnetic arm and its detailed laminated Fact Sheet, this Recovery Curios Original Vintage Aircraft Instrument Collectable would make an unforgettable and highly prized gift for any aviation enthusiast.
This Curtiss SB2C Helldiver Instrument comes complete with detailed Scale Model, Mango Wood Stand & Plaque plus Printed Fact Sheet featuring photo of instrument in aircraft cockpit.
