Voldemort's Wand - how did he get it back?

Hey! I'm new to the HPFGU community, so please bear with me if I 
manage to break any rules!

I was wondering if anyone has ever had any thoughts on Voldemort's 
wand and how he got it back after he was "destroyed" at Godric's 
Hollow. I'm sorry if this has already been addressed - I did a search and couldn't find anything. 

If he became formless and was then forced to occupy the bodies of 
small animals, surely he couldn't have carried it with him? And who 
picked it up from the ruins of the Potter's house?

In CS, he takes Harry's wand so clearly doesn't have access to his 
own. However, by GF we know that he has a wand again, and waht is more we know that it is HIS wand, not merely one stolen from other wizard - it remains the brother to Harry's wand.

The only possibilities I can think of can easily be disproved -
Wormtail gave it back to him - this fails on several points. We do not know how Wormtail keeps his own wand (perhaps he doesn't - I wondered if he forced to acquire a new one once he goes back to Voldemort - perhaps he inherits Bertha Jorkins'.). How would Wormtail as a rat have carried either his or Voldemort's wand, even if he had been the one to retrieve the wand from the rubble of the house?

Lucius Malfoy (or another Death Eater) kept it, along with some of his other possessions (including of course Tom Riddle's diary), and then somehow returned it to Voldemort. This seems highly unlikely - while it might have been possible for Malfoy to retrieve the wand from the wreckage of the house, how would he have returned it to his missing master, and when? There was no suggestion in the graveyard that Voldemort and Malfoy had had any contact since Voldemort's 
disappearance, and the fact that Voldemort explicitly states that none of his Death Eaters except Wormtail sought him out seems to disprove it entirely. It is, I suppose, theoretically possible that Voldemort was using another wizard's wand up until the graveyard scene in GF (for example, to kill Frank), and that Malfoy brought the real wand with him when he apparated in the graveyard and gave it to him then, but this seems the sort of thing that JKR would have mentioned!

So, does anyone have any ideas with fewer holes?
