hey thanks for the info clive , was very interesting to read , wrote it all down & gave the info to my boss .........browny points ....nearly xmas ! . i do have a couple of pics but not sure on how to get them on here ? . my boss had a fair collection of british armour , from a chieftan , cent' arv , abbotts , ferrets , strikers , 434's & 2 's so i;ve been quite lucky really . the collection was sold off recently to marcus glenn, but the pig is staying ! . i myself have a well known type of ww2 american truck.....keeping head down ..... so this has been an interesting time . sure beats working on trucks & forklifts !!
