Scale 1/43.5 or 1/48 African Spur thighed Tortoises (Larger tortoise is 13mm in length, smaller one is 8mm). I model a railway in Sudan in O scale (9mm gauge to represent 18" gauge) and couldn't get suitable animals so made some. The two tortoises are connected at the belly by a sprue and need to be separated carefully using a scalpel (FUD cuts fairly easily, just be a little patient and make lots of small cuts). Suitable for O scale layouts or 40/42mm wargaming. These tortoises would of course make larger tortoises in a smaller scale, or smaller ones in a larger scale.
