For Sale: Complete Record Pista groupset (parts or whole thing)

Hi, this is sat in a box in my shed not doing anything so I figure I should probably sell it to fund the three bikes I've bought in the last week (not sure how that happened...)
It's all from around the same era but it's worth noting that the hubs don't match, though they're both Record.

1. Campagnolo Record Pista crankset 165mm 144BCD.
   I've given it a bit of a polish, but it's not perfect. Very good condition for the age though, I'd say with just a bit of rub in the normal places.
   Threads/tapers excellent. Includes old fashioned or newer style bolts.
   
   

£110

1. Campagnolo Gran sport headset.
   Bottom cup seems to be different as it's not as shiny as the top. This isn't really evident when in situ, tbh.
   Loose bearings, all races in very nice condition. All good.
   
   

Taking different cups into account
£40

1. Campagnolo Record Pista (?) 27.2 seatpost.
   Some marks that would buff out (according to someone who knows about these things)
   £30
   Can include the seat clamp bolt for an extra £5, or for free if anyone takes more than one thing.
   
   

1. Campagnolo Record Pista hubs laced to CXP22.
   Front has some wear but is still serviceable, rear has never seen a brake.
   The front hub is different to the rear, but just different Record groups I suspect.
   Rear hub is single side threaded. Thread seems a bit sticky, but I put a cog on there last night without an issue.
   Bearings are good.
   
   

£120

1. Campagnolo Record Pista (?) English threaded bottom bracket.
   Excellent condition. All threads good, all races good.
   £40 or £30 with crankset.
   
   

Or £320 for the lot.
