Yes please! I'm after two pound straight or cross pein hammers. Preferably wood handle (or no handle). a cross face cross pain would be ideal but very unlikely!
I'll keep an eye open, the place I go to has a completely random selection of secondhand tools. The bloke does house clearances as well as buying lots from the local implement sales.
I've had axeheads, padsaws, torque wrenches (top of the line mega insulated stuff) hammers, chisels, sockets, tap and dies, ratchets, drill bits, more files than you could shake a stick at, file cards, screwdrivers billhooks.
Sometimes he seems to have loads of one thing then not have any for ages.
All sorts of random stuff, sometimes see large circular sawblades (the old ones that don't have Tungsten carbide tips) but I'm not buying one of those unless I know for sure I can move it on.
Got a leather washered 20 ounce Estwing claw hammer you can have (for free if you pay postage) but as I only bought it for the washers it will need re-washering then the pins either peened over or maybe an M6 threaded rod welded on and two nyloc nuts to hold the steel end washer on.
So far I've not seen any hammers like that one you described above but its surprising what turns up there so anything is possible.
