Isn't that a Volpar Beech 18? Tri Gear model

"In 1960, the Volitan and Parigon Corporations joined forces to form Volpar Inc. Volpar went into the business of converting standard Beech 18's to tricycle gear versions.
Pilots who have flown both versions report that in-flight characteristics are nearly identical between the standard Model 18 and the Volpar tri-gear. The Volpar has only two real disadvantages vs. the standard Model 18. The increase in weight of 175-250lbs reduces passenger accommodations by one full place, and the rear-set nose gear strut increases the risk of accidental damage to the now longer nose during tight ground maneuvers. However, the benefits of the Volpar Tri-Gear far outweigh its detriments.
