I am trying to find a Sharp "service" manual for the Sharp R-1830 and the Sharp R-1850 which were used in the 1996 and 1998 U270 coaches.<br/>I did not have any luck with "search" therefore, I am hoping someone might have them in their personal collection.<br/><br/>I do have a copy of the Sharp service manual for the R-1870 and R-1871 if someone needs it.<br/>Regards,
