This pack comes with a wooden barrel, oil drum, cable drum, pallet, tyre, sandbag and brick stack. Some models are in both 00 gauge and N gauge and some just scaled for N gauge depending on the needs of the model for printing. 
 
For models with only an N gauge model: for TT:120 the model can be scaled by 125% and those modelling in 3mm can scale the model by 150% and those in 00 gauge can scale by 200%
 
For models with both 00 gauge and N gauge: for in TT:120 the N gauge model can be scaled by 125% and those modelling in 3mm can scale the 00 gauge model by 75%.
