Two local gun shops have trapdoors.
1879 - nice over all. Excellent looking bore. And about $1000. Not an expert, but probably worth that based on gunbroker looking. 1879 rear sight. Great finish.
1888 - excellent looking bore. Exterior metal - portions look like it was stored in a barn. Buttplate is the swinging trapdoor and pitted. Muzzle, exterior, is slightly pitted. Front sight blade replaced with higher one, not very well done, can be clean up. Really not bad looking gun, all functional. Rod bayonet type. Buffington rear sight. A little more exterior pitting.
About $450
Both guns are all there, I would not be embarrassed by either.
The $1000 is definitely nicer, but twice the price.
Which one should I buy?
Collection yes, but shooter first.
Don't beat me up on the wrong models and dates. At least yet.
1870 rear sight
rod bayonet and Buffington rs.
