If truly in nice condition and with its upper handguard (very, very important), the RIC carbine could be worth $1,200 retail (less at auction). As for $4,300 for the civvy Lee-Metford, I'd say that's about $2K too much. Pics would help. Though it's a little out of date, see my price guide here:2009 Lee & Martini Price Guide, Coggansfield in Martini-Henry Forum Forum .
