Unfortunately 190009 is not in the Serialization Book so we can only presume it is as it was manufactured. 30" barrels were one of the standard barrel lengths for the 12 ga. Trojan (30", 28", and 26" being the standards) but 12 ga. Trojans were made in every barrel length from 23" to 36" but only 14 that we know of were made with other than the three standard barrel lengths.
Please post more pictures for us.
