All sales benefit the Northern Pacific Railway Historical Association. They are offered on a first come first serve basis. All requests must be in the form of an email to rrbrakeman@aol.com. Prices vary depending on the size of your purchase in one transaction. Majority of items are still factory sealed and in storage making photographes difficult. I am not an historian and cannot do prototype research for you and I am handling the sale in my spare time so have patience. PayPal, friends and family, is the preferred method of payment but other forms will be considered. If you see an error in the listings please do not hesitate to send a corrrection. I ship exclusively with USPS Priority Mail. Local pickup available in the Seattle area.
