Hi I have a Matchless 500 that has been rebuilt but for me. To get it licensed to use on the road, I need to find the chassis number. I have looked in all the advised places but the only number I can find is A58220 can anyone confirm that this is the correct number and give me any info on the bike if this number is correct. Engine number is 57/G80s131496.

Hi Alan,

And welcome!
If that number is the one that is stamped on the right hand side in the vicinity of the headstock then that is your frame number. As far as information on the bike, aside from a 1957 Matchless G80S, there isn’t a lot to say. AMC didn’t have matching engine and frame numbers. If you were to look up the club in the U.K they could (at a cost) provide you with a certificate of the bike and where it was originally sold , if it was a police bike for eg etc .

Good Luck with the bike.

As said above the number should be STAMPED into the frame.
Anything in raised lettering/numbers is a casting number.
The blurb about finding the frame number is a little unclear.
It sez up to 1957 its under the seat, and from 1958 its up front.

Your A prefix number fits into the series of yearly numbers listed
for 1956/1957 in Roy Bacons Ajay and Matchy resto book.

You G80S should look something rather like this for 1957.
The 350cc and 500cc versions were near identical, except for the engine capacities.
Minor details could vary a little for specific markets.
