Hi
Are you in the UK?
Quoting from Vic Davies; "As regards re-finishing, if you want to do an authentic re-paint job, you would theoretically need to apply seven coats - which is literally what we used to do (if you include jenolising and priming). The down-tube decal might be available from the Ulster company which still uses the Viking name"
You can get a number of Viking decals here;
