TGB's Beater Bonanza - cheap/swaps

All for collection from south east (SE6). But I could potentially deliver smaller parts locally on Thurs/Fridays.

All priced up to sell, but I would prefer some swaps, looking for:
A road saddle, a road triple front mech, 8 speed compatible and a rear brake caliper.

Thanks for looking!

How much did you want for the SA thumbie with 8 speed shifter? Sorry if I missed it in the list. I might have a seatpost and will check on front derailleurs (have a bunch, not sure on speeds etc). Will get back to you this eve if ok.
Edit, also interested in Topeak saddlebag...

I’ll have a look at the mech for u, might have one upstairs. Cheers. T

@adamdenw This one is up for £10, thanks!
