I'm enjoying this Ideor thread but I really miss my 1958 Ideor. Fortunately I still have my 1961(?) Ideor which is a keeper. Not 100% sure of the year but it does have Universal 61 centerpulls and the non drive side crank arm has the raised pedal lip. Drive side crank probably cracked as it is newer(no raised lip).

Here are some pictures. Anyone else, including the OP have any Ideor pics?
