Keith Sivyer, from Twickenham, began his stunning archive from the inception of the UK single charts in 1952
Every week without fail, he bought the latest records to add to his collection until his death at 75 in February
Now, his younger brother Gerald has the daunting task of unloading his late sibling's treasured possessions
Archive has been divided into three lots for auction - and 10,000 CDs and cassettes could be yours for just £600
A dedicated record collector bought every single that made the UK charts for more than six decades, leaving him with a collection of more than 45,000.
Keith Sivyer began his stunning archive from the inception of the UK single charts in 1952 - and continued it, cramming his tiny terraced house in Twickenham, south west London, full until his death this February at 75.
Every week without fail, he had visited his local record shop with a copy of Music Week under his arm and bought the latest songs that had entered the top 40 before going home and adding them to his trove.
His younger brother Gerald was left with the daunting task of unloading his late sibling's treasured possessions.

He found around 27,000 seven-inch vinyl singles and 8,000 12-inch singles neatly filed in alphabetical order on purpose built floor-to-ceiling shelves that covered the four walls of Mr Sivyer's lounge.
More than 10,000 CD singles from the 1980s to the present day also filled up a spare bedroom of his modest home.
There were dozens of CDs still in their cellophane wrappers from where he had not had the time to open and listen to them.
Mr Sivyer had safely stored the covers for most of the singles and replaced them with white sleeves on which he wrote the date the song was released and the chart position it achieved.
Auctioneers don't believe there is a single single missing, although admit it would take weeks to trawl through them all to make absolutely sure.

Alastair McCrea, of Ewbanks Auctioneers of Woking, Surrey, was invited to Mr Sivyer's three-bedroom house to value the collection.
He said: 'The front room was wall to wall covered with shelves with the seven inch singles on, the only space that wasn't taken up was where the window was.
'It is really was impressive to look at. These days most people have their entire record collections stored on a small digital device in the living room that can been accessed remotely.
'Apparently, Mr Sivyer was not that up on technology and terms like 'downloads' and 'back-up' would have been completely foreign to him.
'It was a passion and an obsession for him.
'We believe the collection to be one of the most complete and possibly unique in private hands in the country. We can't guarantee for sure it is absolutely complete because it would take months to go through every one but we think it is.'
He started his collection in 1954 at the age of 15 and retrospectively bought all the singles that had entered the charts for the previous two years.

Record shop owner John Carroll said he had gotten so used to Mr Sivyer's custom that he put the records aside for when he came in.
As his collection grew, he naturally became a mobile DJ although he also worked for 37 years as an airside worker for British Airways at Heathrow.
When he divorced from his wife in the mid-1970s, he moved back in with his mother Louise along with his collection.
His brother Gerald, 68, a retired builder, said: 'It became an obsession with him. He must have spent an absolute fortune by the end.
'Most of the singles were bought in the week they were released from a record shop called Earfriend.
'When the shop closed, he started buying them from Woolworths and then off the internet in recent years.

'I had to reinforce the floor of the house at one point because of the weight of the boxes he kept some of the the records in.
'He then took over the whole front room and started putting up these shelves.
'He used to drive my mother mad. When I went to visit I would notice the collection was just growing and growing. It was crammed in like sardines.
'He did tell me before he died that one day it would all be mine and I asked him what on earth I would do with it.
'I would have loved to have kept them and if I had a big house I would have but I live in the first floor flat and it is just not practical.'
The collection has been divided into three lots for the auction, with the 27,000 seven inch singles conservatively estimated at £6,000, the 8,000 12 inch records at £1,500 and 10,000 CDs and cassettes at £600.
The sale takes place on May 21.
