Hi MB Its funny I was ready thru the Haynes manual this morning and the frame number example was a GA10 number. You should email the VMCC library and see what they say. Jeff
Try Ian Jackson U K BSAOC , he has a lot of dispatch records , if he can't help from his records , he may be able to point you in the right place to get some help. ian@ralphtall.com RGS-BILL
