Last few years comma we have presented various results of high-resolution spectroscopies of SNRs with the RGS. Although a large amount of the archival data over the past twenty years is available and most of the notable SNRs have been observed with the RGS comma several intriguing remnants are still not observed. A recent comprehensive systematic analysis of SNRs revealed that a clear correlation between their morphologies and supernova types. We comma however comma found two outliers in the correlation diagramdoublePoint 0548-70.4 and 0104-72.3 comma which are minor LMC-SMC SNRs but have anomalous abundance pattern and peculiar morphologies. We thus propose to observe these SNRs with the RGS to give a conclusive result on their origin and nature.
