ElectroCraft Servos

Does any one have an old ElectroCraft Catalogue that can give me the
specs for a model E543 Servo with 250 CPR encoder(not so old really
manufacture date is 1998). A search of the web has established that
ElectroCraft has gone the way of all good companies. Swallowed up by
AB who was swallowed up by Rockwell etc. Thus there is a black hole
of information as these companies' web sites get closed down. Also
have the same problem with Reliance for a model E240. Both types are
brush DC PM servos. Can anyone help?
TIA
