Warning - the photos make these look better than they are.....
Pair of 20VT Brembo four-pot calipers - were silver, but now (badly) painted red.
They are seized and will need to be fully stripped and rebuilt with new seals, dust covers etc (as well as a fresh coat of paint)
I have not attempted to dismantle the calipers, so I have no idea how good or bad they are. You might get away with just new seals and a quick clean of the pistons.
£50 the pair, plus £10 P&P
