from The National 2½" Gauge Association

List as at May 2008

THIS LIST SUPERCEDES ALL PREVIOUS LISTS

THE WHEEL RANGE

The list shows the current range of 41 different wheel patterns with their main dimensions and features. To ensure that the nearest correct wheel is identified do mention the locomotive type when ordering.

AVAILABILITY

Every type is generally held in stock, but inevitably there may be times when there is insufficient to meet an order. Restocking may take up to 8 weeks.

COSTS

All our castings are available to members and non-members. A portion of the monies raised by member's subscriptions was used to fund the purchase and manufacture of the patterns. Thus, non-members must add 10% of the cost to their order.
