Went to the biggest Antique fair in Europe today. Newark Fair. picked up a couple of bargains ....an '85 CWC Quartz military watch (£10), with original regimental strap, and this beast. for £30 i thought what the heck!!
It's sprung, and apparently has the Lancaster? attachment on it. As normally when stored it's just the top part within a grey wooden box.
Part numbers 6A/893 for compass & 6A/366 for the base
