Spotted this on ebay, listed as a WW1 first aid kit. It looks an awful lot like the lighting kit box on the 25 pounder but with some variation. Is this box possibly off an 18pdr or some other earlier artillery that used the dial sight? Size is given as 36cm high x 25 cm wide. I am adding a photo from Tony's thread showing his box for comparison. I am after the 25pdr box....the one in the auction appears to be earlier, and is not cheap so I am adding the link here in case someone is interested.
