We present results from modeling the broadband X-ray spectrum of the Type 1
AGN 2MASX J193013.80+341049.5 using NuSTAR, Swift and archival XMM-Newton
observations. We find this source to be highly X-ray obscured, with column
densities exceeding 10$^{23}$ cm$^{-2}$ across all epochs of X-ray
observations, spanning an 8 year period. However, the source exhibits prominent
broad optical emission lines, consistent with an unobscured Type 1 AGN
classification. We fit the X-ray spectra with both phenomenological reflection
models and physically-motivated torus models to model the X-ray absorption. We
examine the spectral energy distribution of this source and investigate some
possible scenarios to explain the mismatch between X-ray and optical
classifications. We compare the ratio of reddening to X-ray absorbing column
density ($E_{B-V}/N_{H}$) and find that 2MASX J193013.80+341049.5 likely has a
much lower dust-to-gas ratio relative to the Galactic ISM, suggesting that the
Broad Line Region (BLR) itself could provide the source of extra X-ray
obscuration, being composed of low-ionization, dust-free gas.
