This is a kit release and that is the box art that I posted earlier. Will be in 1/72 as Frank said. Thus the kit will be ~39cm long, and with a wingspan of ~74cm.
In civil transport configuration, the K-7 would have had a capacity for 120 passengers and 7,000 kg (15,000 lb) of mail.

In bomber configuration it would have been armed with 8 x 20mm autocannons, 8 x 7.62mm machine guns and up to 9,600 kg (21,200 lb) of bombs.
