Maybe with that monoblock, someone had thoughts of building a double rifle in something like 45-70 or 50-70.
Lot's of work in that monoblock, the Parker action wouldn't be a first choice for an action for a DR conversion. But with a low pressure round and kept that way, it'd work OK.
Check over on the Nitro Express. com Forum under the 'Building Double Rifles & Gunsmith' section..
You'll have to sign up first and then log on to get to the forums but they are worth the effort. Doesn't cost anything.
There a poster there that goes by Birdhunter50 that makes and sells top ribs for DR conversions (they have integral 1/4 rib and front ramp) as well and bottom ribs and has occassional bbl blanks for sale as well. Had some 12ga rifled blanks recently.
Lots of info & pics over there if you want to in that direction.
Fun projects,,but again a labor of love.
