I have surplus to requirements (ie they have been collecting dust) 3 hip flasks I have received over the years. They all have logos on them.
One on left of photo has a logo consisting of 3 decorative keys crossing each other and is a 6oz pewter job
Centre one has Citigroup near bottom face of flask and has "Edwin Blyde celtic collection" on base. Also pewter
One on right has "Midland Montagu Clayshoot chenies manor 1989" etched on front and is a 3oz pewter effort.
I'll give them all a buff before despatching. How about £7 for central one and £6 for those on outside including postage. For the true drunk £15 for all 3 including postage
