A bit hard to say,but most originate from barbra wiltshire who imported 6 in 1965 and bred some 84(mostly male) from them.These were all sourced from the pet trade which were no doubt wild caught imports from who knows where?Yugoslavia,morroco,tunisia.
ivan had a big huge female his place for a while and we summised that by its colour and size could be an ibera?There are also others around from various origins??
