Squash ID please (photos provided)

This squash vine self-set in among my peas and I allowed it to do its thing - live or die. Now the peas are cleared the squash vine has taken up residence and has a good number of fruits.

They don't sound ready when you tap them (sound too solid) so they have more growing to do, but I don't know what they are.

Does anyone recognise the vine or the fruits please? The leaves appear like Courgette leaves but the growth pattern is a creeping vine rather than a central stem rosette.

The fruits start pale green, deepen in colour and then become more golden as the attached photos.

- a "Butternut Marrow"? 

- so a kind of marrow? - which would explain why they sound a long way from maturing yet - they don't tap right.

Marrow Rum for Christmas then!
