Lloyd, I believe you may be referring to the Bing Crosby Lang & Hussey 28? Here are the selling notes from that gun, from my records, which also indicate that HJ Hussey would have made this gun in 1893:

"Lang & Hussey Imperial Sidelock Ejector, circa 1894 very early and rare 28 bore sidelock, original fluid steel 28" nitro proved chopperlump barrels and proved 5/8 oz. with a concave game rib engraved "Lang & Hussey Ltd. 102 New Bond Street London" and choked .038 ridiculously extra full and .045 ridiculously extra extra full, another set of fluid steel 28" barrels added later but pre-1950 and also London nitro proved but proved with rare extra long 2 7/8" chambers and for a 7/8 oz. load with a wide flat and high pigeon rib with tubes engraved "Lang & Hussey" and "London" and choked .007 Lt. Mod. and .012 Mod., very dark and moderately figured stock with 14 5/8" LOP over a red Silvers pad, 1 11/16" DAC, 2 1/2" DAH, 1/4" cast off, splinter forend, straight grip, double triggers, drop points, 5 lbs even (game rib) and 5 lbs. 8 oz. (pigeon rib), bar action 7-pin sidelock with fine rose bouquet and English scroll engraving with "Lang & Hussey Ltd." on both sides and "Imperial Ejector" on bottom of action, ejectors, non-automatic safety with "Safe" in gold, cocking indicators, vacant stock oval. Condition: about 70% case colors remaining, some thinning of barrel blue, a professionally repaired crack from right side of trigger guard extension into checkering that looks sound, some wood repair behind the stock oval on the bottom edge, pigeon rib barrels bores .553 on both and .027 and .029 min. wall thickness, game rib barrels out of proof with bores .565 and .568 and min. wall thickness of .015 and .017, game rib barrels also have chambers lengthened to 2 7/8" to match other barrels but not reproved. ... Additionally, when this gun was previously purchased from a dealer no longer in business, it was said this gun belonged to noted Actor, Singer, and Sportsman, Bing Crosby. At the time there was a document from England made out to Bing's widow's name for repairs made to the gun. Unfortunately, that document is no longer with the gun. It is well documented that Bing was an avid 28 bore user and also that if you hunted with Bing, he insisted that you also use a 28 bore. We have confirmed that Bing's guns were sold at a May 1982 of all of Bing's personal items at Butterfield and Butterfield in San Francisco. We are trying to obtain a copy of that catalogue to document this gun but at this time we have been unable to complete that. Rest assured that if/when we do, the price of the gun will increase. On it's own a rare early Hussey Imperial in a rare and desirable bore size and a rare heavy proof and long chambers." For sale with MW Reynolds in Denver 2014. Here is a photo of the gun:
