I'm sorry if this post is redundant, but I'm looking for some help. I"m a newbie and found a bike for sale WITHOUT the wheelset for 500 ducks . The guy says its quality Japanese steel, but I've never heard of Omni

here is his description:

It is an Omni built with 973 superlight bouble butted tubing, lugged
frame painted medium metallic blue with an extremely nice chrome fork,
it will take brakes and fairly large tires, rear facing track ends.
Sugino track cranks and bottom bracket, Tange track headset, SR cold
forged stem and track bars, SR track post and Kashima saddle, MKS track
pedals.

Any advice/thoughts?
thanks
