Table 3: Eleven stars towards 3C 434.1 with observed reddenings that are consistent with that observed toward the SNR/SWB ( E(B-V)=2.1 mag), i.e. $1.7~{\rm mag} \leq E(B-V) \leq 2.5$ mag. The uncertainty in the assigned spectral type is on average plus or minus one sub-type (e.g. an O5 is O4-O6 within uncertainty). Distances are calculated using reddening law RV=AV/E(B-V)=3.1. All distances have an uncertainty of $\pm $30%.
