I bought one of those back in 1985, the original from Tandy in UK
Its same as the Uniden 2021 i think and the Sangean440, number unsure.
I think they were made for RS

You have a great bargain there, there are quite a sensitive receiver, i used
for many years for MW DX from the Uk and logged dozens of US/Canadian MW
stations
