I have a VL&D catalog which shows the Knockabout.
Francotte action, Greener cross bolt, Nimrod steel barrels. 10, 12, 16, 20, 28 and .410 available.
The catalog lists this as the 'new' Knockabout, a boxlock, and mentions the old version, a sidelock, had less features.
$165 w/ extractors, or $200 with ejectors.
It also notes that no import gun can approach it at the price, and no American gun can match it for balance, model, and strength for weight.
Call me crazy, but I would have rather had the Parker CHE for $20 more. Or the Purdey sidelock with Whitworth barrels for 140 pounds. Or the fully engraved Purdey high power hammerless express double rifle for cordite in your choice of chambering for 143 pounds. Yes, a good old .470 NE Purdey double rifle would have been my choice over the Knockabout.
Cameron, if you want a copy of the catalog page let me know and I will email you a .pdf of it.
