fleaMy search through the internet suggests this is a model supplied into Asian market - at least I have found Mudmasters with this model number in Indian, Indonesian and South African (?) shops. It does have LED back-light according to the descriptions in those shops and I believe the location of assumed sale is the only difference from 1A5 model.
However I'd like to hear opinion of anyone knowledgeable on this topic.
- LED backlight (Auto LED Super Illuminator Backlight, selectable illumination duration, Afterglow) Neo-brite Luminous Hands and Markers
However this is a model 1A5DR and no mention.
