A prior owner had for some reason, overpainted the original inner case lid label on this No.71. Since the case paintwork was also in a generally tatty state, I decided a while ago, to remove both the incumbent corrosion and paint by electrolysis back to bare metal in order to undertake a respray - VHT silver paint, good for 800C /1472F was used. Big thanks to Ross (@Spiritburner) who recently sent me a high resolution photo of the inner lid’s Primus label for me to reproduce, enabling me to complete the restoration. No date stamp either on the base or anywhere else on the stove. Pharael.
