We present evidence supporting a SNR origin for the radio source G337.2+0.1 , which was discovered along the line of sight to the Norma spiral arm in the MOST 843-MHz radio survey . The radio source is spatially superposed to the unidentified ASCA source AX~J1635.9-4719 . An analysis of this latter source reveals that its X-ray spectrum , extended nature , and non-variable flux are consistent with what is expected for a SNR . In addition , we have used HI-line observations of the region to look for any effect of the presumed remnant on the ISM . We have found a well-defined minimum centered at the position of the radio source in the velocity range of \sim - 25 to -19 km s ^ { -1 } . This feature appears as a sharp absorption dip in the spectrum that might be produced when the continuum emission from the SNR candidate is absorbed by foreground gas . Hence we have used it to constrain the distance to the source , which seems to be a young ( age \sim a few 10 ^ { 3 } yr ) and distant ( d \sim 14 kpc ) SNR . G337.2+0.1 and AX~J1635.9-4719 would be the radio/X-ray manifestations of this remnant .
