This is the only image I have for the item. http://assets.nationalbuildersupply.com/ul_pdfs/SS-00366_CST794EF.pdf">here is the spec sheet that has an additional diagram. Toto offers many trip levers. The toilet would come with one but you can look at additional ones to order http://www.supply.com/tank-levers/c371?src=lhn&d=371-1056">here. As far as the letters, C (Double Cyclone Flush), D (insulated tank), E (E-Max 1.28 gallon flushing), F (comfort, ADA height), G (Sanagloss finish). The R in this model number indicates that it has a right hand trip lever.
