In bottom left just inside border in small script Perkins, Bacon & Petch, London. Patent Hardened Steel Plate.
Back : Spirographic design
Watermark : None seen in BMC issued Rs10 note. Printed : Perkins Bacon & Petch, London.
Size : Estimated assuming Frame is same as circulated Rs 5 note measured from the Colombo National Museum Collection, and assuming size was adopted in inches. On Rs10 denomination the same Royal Charter Engraving was assumed to be of same size.

Note the absence of any Sinhala or Thamil text in this early undated colorless Proof,
which appear in the undated Kandy Specimen note issued in the 1850's and the 1854 issued Rs 50 notes as well as the older notes. So maybe, just this Proof that lacks Sinhala and Thamil and not the issued notes.
I thank Thomas Hockenhull of British Museum for confirming that Sinhala and Thamil Text appears on issued Rs 10 note, and name of Printer. CIB.15751 1^st July 1853 OBC Rs 10 with Serial Number C33713(BMC) was imaged with permission in Study Room on 2023 May 25th.

I thank Jonathan Callaway for reference from his The Perkins Bacon Story 2015 Winter Spink Insider Issue 23 page 32.
