Got this lovely postcard in the post this morning - this is the photo used on the ebay auction until I get my scanner working again
As well as liking it because I love the old Motorcycle's, it's also interesting looking at the detail - what appears to be a 'made in the field' mudguard on the body of the bike in front of the engine, unusual goggles worn by the rider, no signals blue and white armband, no shoulder titles, 03 belt usually worn as a trouser belt but used as a waistbelt on the SD jacket, civilian girl sat/stood in the sidecar, and the registration plate with nothing on it except the WD broad arrow. The detail is fantastic, considering it's at least 90 years old - this era never ceases to fascinate me
