From Cowan's 01 May 2019 sale Lot #8:
40 caliber, 38.25" wedge retained octagonal barrel, no S/N. Browned finish, brass furniture, full-length hardwood stock. Barrel signed LWP in script, otherwise unmarked. Reconverted flint lock with fenced water proof pan, roller frizzen and added flat, beveled swan neck cock. Roman-nosed stock with awkward, paddle-like profile set with four-piece acorn finial patchbox in obverse and smaller oval patchbox in reverse, under cheek rest. Buttplate with separate toe plate, triggerguard with extended finger rest, double set-triggers, thick two-screw side plate. Decorated with a German silver six-pointed star on the cheek rest and a pair of brass fish on either side of the forend between the lock and rear sight. Forend spliced at entry pipe and replaced to muzzle. includes a wooden ramrod.
Seems like a reasonable overview and description, especially with the photos provided in the online catalog; the spliced forend is noted as well.
