You're right, Wladimir. It doesn't look like the other ell shapes. It has a bend and a dotty thing to the right. It's quite possible it's a "k".
If it is a "k", then it's probably not Latin (badly spelled), it could be eastern European (eastern European languages also used Latin abbreviations, so the ending is not unusual... that shape can be -orem, -rem, or -em, and occasionally other endinigs). And... it could be some western language depending on how well the writer spells.
