1946 BSA M20 EX ARMY CLASSIC MOTOR CYCLE

1946 BSA M20 500CC SIDE VALVE EX MILITARY MOTORCYCLE HAS BEEN OWNED BY THE LAST KEEPER SINCE 14TH JULY 2000
I BELIEVE THAT IT WAS LAST ON THE ROAD IN 2009 AND HAS BEEN STORED IN A DRY GARAGE SINCE THEN I HAVE GIVEN THE MOTORCYLE A GOOD CLEAN REPLACED THE ENGINE OIL,GHECKED THE PRIMARY DRIVE AND GEARBOX OIL.
REPLACED THE SPARK PLUG AND TREATED IT TO A NEW SPARK PLUG, BATTERY AND CARB OVERHAUL KIT IT STARTS EASILY AND RUNS WELL.
THERE IS A RESONABLE PAPERWORK FILE WITH OLD PICTURES AND MOTS ETC.
THE PICTURES ARE PART OF THE DISCRIPTION. VIEWING IS HIGHLY ADVISED.
I have received some messages regarding the frame and engine numbers which one person has said do not relate to an ex army bike. I have included some pictures of the frame and engine numbers and one of the log book. These are there to help people research. I have no paperwork to confirm whether it is or not.
