Since I'm going to restore an 8x10 from the early 1900's decades I figure that I should add an appropriate lens to it.

Any recommendations on something representative for portraits and landscape, which would be moderately wide angle (250mm or so?) and won't break the bank?

The camera has a 4.5" square lens board and only very basic movements.

Negatives are going to be contact printed to regular photo paper and maybe carbon if I get to feeling saucy next year.

TIA
