I am about to start a restoration of a basket-case Norton Atlas. The slimline featherbed frame has a frame number 20/105*** and this has me a bit concerned. Information I have seen elsewhere suggests that Atlas frames started at 20/108000. Could this refer to only UK Atlases? I have seen Atlas crankcases for sale on the US Ebay with numbers starting 20/105*** so might my bike have been a US import? I have no documentation with the bike. Can anyone clarify this?
 
The Atlas was sent to North America before available for the UK market. I think that's the origin of 20/108000 VIN number.
 

Have a look !
 
My Atlas is a ‘64 and it’s a 20/1055**, so it would appear you have a US model
 
If its a US bike then its likely been imported at some point, if you have no paperwork then stop now. You need to get it Nova'd by HRMC retrospectively (but they will not like you calling it retrospective so don't ask !!), dated by NOC etc.
