On the way back we called in at a bric-a-brac shop at Darfield, where I found these.
The vice is a Record 52½, in very good nick, and it cost me $128 — about a third of what it would cost me to buy one new. I've been looking for a decent vice for ages, so this is an excellent score for me.
The brace is also in excellent nick. Because nobody much uses them any more, they're a lot more expensive to buy than they used to be... Bunnings has them for $175. This one cost me $24, and the lady threw in the bits for free.
All in all, a very productive picnic.
