The Wellington was the mainstay of BC from day 1 of WW2, until the first of the 4-engined "heavies", the Stirling, entered service in January 1941. The re-hashed manchester aka the lancaster, didn't enter service until February 1942.
The Wellington was the only British-built bomber to see continuous service throughout WW2, and was in continuous production (over 11,000 built) from the late 1930's until October 1945. By comparison, there were only 7300 or so lancasters produced.
By and large, the Wellington was under-rated - it was the only viable means of attacking Germany to any degree AT THAT TIME. Give it the recognition it deserved........
