I sure like my G5 Deluxe but there is a certain "old time" appeal for the B5.
Those tank badges on the B5 are so "art deco" they just spell
"O L D" to me.
The photos in "Royal Enfield, By Miles The Best" show them first appearing on the 1953 Model G, J, the Bullet and the Meteor.
By 1956, the regular Royal Enfield Bullets had replaced them with different tank badges.
I know all about your frustration in waiting for your new bike. Been there, done that.
Attached is a photo of my G5 Deluxe right after I first rode it home from the dealer.
