US-$ 5.000 (if that high)? If the pelham blue is original, that would generally fetch a much higher price, but the neck break taketh away (and more) whatever the color giveth.
I'm coming from what I paid for my four 60ies Birds (all sunburst, three unbroken) pre-financial crisis. That was around US-$ 5,000 except for my NR II which needed a severe neck repair and was in horrible shape.
If prices are now indeed higher, I'll be delighted - wow, value increase of ze kölleckshün!!!
Mahogany Birds are never heavy. Today's maho might weigh more than what they used in the 60ies, but that still doesn't make these basses shoulder benders. Anybody not accustomed to a TBird will always be surprised about how light it is. Same with Explorers.
