Based on the tag and serial number it should be a 1983 or 1984 model PH11 in 54 cm size, but this model does not show up in my US catalogs for those years. It could be a foreign model. Regardless, it should be one of the upper, entry level models with lugless, Carbolite 103 tubing. I'm assuming it is roughly equivalent to a PH10 which cost about $250 US during this period. Having pics would help us correlate it to known US models.
