BSA Bantam 175 4 speed Trials barn find restoration project spares or repairs

Up for sale is a nice old BSA Bantam 175cc, as shown it has been off the road for some time but was a runner when laid up, run wear is all solid engine kicks over with good compression and gears select ect.
4 speed engine with centre plug head, heavy weight forks.
I do not have the v5 for the bike so will need to be applied for, frame number is visible but I can not find a engine number, has it's number plate so easy to apply for.

Please study all of the pictures as they give a better description, all the tin wear is solid just surface rust ect. no rot.
So just to be clear it has no v5 document full receipt will be issued.
In short a good solid bike and with not much effort will be back on the road in no time, only selling due to ill health.
