Low-resolution spectrophotometry in the region 6000-9500 A was performed for three AM Her-type systems, with the Isaac Newton Telescope, and UKIRT photometry was performed for two of them. PG 1550 + 191 (MR Ser) was found to be in a low state; the others, CW 1103 + 254 (ST LMi) and E2003 + 225 (QQ Vul), were not. In all three cases, spectral features characteristic of late-M stars were detected. In addition the infrared photometry of two of the systems are reported making it possible to refine the distance estimates.
