I wouldn't hold out too long for a 30-30, these rifles were only produced for 12 years. 1928-40. there are damn few of them left, in any caliber! They were made on 250-3000, 300 savage, 30-30 and 30-06. The 250 and the 30-30 came with 22" barrels, the other two with 24" tubes. They had two locking lugs which engaged the receiver just ahead of the bolt handle, which acted as a safety lug. In "Bolt Action Rifles" Frank De Haas mentions them in passing. He has little to say about them, either good or bad, because he had never touched one.! They are uncommon to say the least. He does list the discontinuance date as 47. Nineteen years is still a rather short production run.
I hav a few guns that I consider "Holy Grail" guns This rifle is one of them, along with the 1920 sporter. Google THAT one and be prepared to drool....
