Not mine, but there is no model number stamped anywhere that I can find. I know most of the time the model number is stamped on the crane, but not on this one. Thanks for the reply
If there isn’t a model number stamped it’s a K-22 Masterpiece. The Standard Catalog is only a basic guide for serial numbers and approximate dates, they only way to know for sure when it was shipped is a factory letter. The transition to model numbers didn’t have a clear cutoff date.
