Connah’s Quay, Flintshire born left back Bert Lumberg began his football career with Flint Town in 1923 and played the same year for Connah’s Quay & Shotton before joining Mold Town in 1924 after an unsuccessful trial with Liverpool. He signed for Third Division (North) club Wrexham in November 1924, making his Football League debut at Chesterfield in January 1925, soon establishing himself as a regular in Wrexham’s first eleven and missing only one match in their 1928-29 campaign as they finished third in the League.
His consistency came to the attention of the Wales selectors and he won his first international cap in a 2-2 draw with Ireland at The Racecourse Ground, Wrexham in February 1929, winning the last of his four caps in a defeat to Scotland at the same venue in October 1931.
By then he had been signed by Second Division Wolverhampton Wanderers in May 1930 after 178 appearances for Wrexham. Although a fringe player throughout his three seasons at Molineux, indeed during their Second Division Championship winning season of 1931-32 he made only one FA Cup appearance for the Wolves first team, he played 9 top flight matches during 1932-33 before joining Brighton & Hove Albion in June 1933 after 22 appearances in old gold and black.
He had a single season at The Goldstone Ground, making 21 appearances for Brighton, before joining Stockport County in May 1934, but he managed only two matches for The Hatters before moving to Clapton Orient in January 1935, where he failed to make a first team appearance. After a brief spell with non league Lytham in 1935 he returned to Football League action with New Brighton that November, playing twice for them the same month before joining non league Winsford United in 1936.
He moved to Irish League club Newry Town in 1937 before returning to Wales to join Rhyl in 1938. He then returned to Newry later the same year before his career was interrupted by the Second World War. After the War he played for Mold Alexandra in 1946 before his eventual retirement.
