Rare Georgian British Officer's 1800 -1812 Stovepipe Shako Plate (Silver-wash Finish)

An exceptionally rare Napoleonic period British army officer's 1800-12 stovepipe shako plate with a silver-wash finish, most surviving shako plates from this period are plain stamped brass, some even still retain their original gilt finish but never before have I encountered one with a silver-wash finish nor one with a modified rear fixing.
The finish has been lost to the high points due to polishing leaving a lovely colour tone to the exposed brass, there are no perforations to the plate apart from the purpose made fixing hole at the top, the rear is in wonderful condition and there is evidence of removed side fixings, possibly prong types to bend over , what is most interesting is the additional centre bracket with two partly swivelling bars that may have passed through some stitched loops to the front of the stovepipe.
Please study all images in regards to condition.
