Old Vehicle registration

Hello
I am seeking some help and can't find anything via google.
Speaking to local Greeks, I just get the answer no, it's not possible, but I can't believe it's “ not possible “.

Re registering a vehicle that has no paperwork.
Example an old motorcycle. Barn find as we would call it in the uk. Can be purchased with written receipt from current owner, but no registration documents. For whatever reason, fathers died son/daughter have no idea, other than it was their fathers.
I know it's greece but there must be away.

Try contacting the DVLA?

EOT-GRAFEIO PLIROFORION KERKYRAS...Ministry of Economy,Infrastructure,Transport,Shipping and Tourism Corfu..00302661037520..4 Evangelistrias Street 491 31 Corfu.My husband who is Greek says you should ask at a ministry of transport office.He says its a bit tricky as it might look like you stole it having no papers but the family are giving you proof of purchase which they can confirm,worth a try and then you will have it from the horses mouth,and there might actually be a way of solving the problem.

Thanks I shall give it a go.
