Help Ex Serviceman purchase a Prosthetic Leg

Hi, my name is Jeff, ex British Army Sgt and NHS Ambulance Team Leader with SCAS. At age 67 I developed a blood clot in my leg causing it to be amputated. I am retired and have promised my friend that I will walk down the aisle at their wedding in September. Please donate to my cause to help this promise come to fruition, I call on all my friends, former colleagues from everywhere. I know this is a big ask but thankyou all in advance.
