George, I saw this gun being offered for sale. I informed the person who would be interested, a chap called Peter McGowan. If he hasn't already been in touch I can put you both together via e-mail. That particular gun interested me as 899 was my old service number which I carried for 30 years. The workmanship that went into the locks to fit that crossover stock showed the work of a real master. Peter has done a lot of research on Fuller. Lagopus.....
