prospective 5" Hunslet 0-6-0

[only1avro]

Hi all
Having some 16mm projects on the go I am looking longer term at the Don Young 0-6-0 Hunslet (jack) has anyone any helpful info. Among the many things I know little about, The off centre wheel balance weights, the only pictures I have found are of inside valve gear and are quite different to the drawings which are for outside valve gear. The siteing of injecters etc can wait but to cast the wheels is an early job!!
