Of course it does. A model that changes from P&R to not makes a difference. A model before the Hillary Hole will command a better price than one with that contraption. Certain modifications are desireable, others not so much.I've also never even seen that a particular "dash number" made much difference in the price
Ahhh..... Okay. Now I get it!A dash between MOD and 36 (like this MOD-36) isn't what the "no dash" moniker is referring to.
A no dash is the first version of model.
For example: One marked MOD 36 (or MOD-36) is a "no dash" because the next iteration would be MOD 36-1 (a.k.a. Model 36 FIRST revision)
Think of the "no dash" as being a MOD 36-0. There were never any gun versions marked as dash zero (-0), they are what is referred to as the NO DASH (first) versions of the model.
...and then there is the model 13 which was introduced as a 13-1. There never was a 13 no-dash.Usually the dash (engineering changes) don't make much difference since they're just a way to simplify (lower) production costs. However, if you happen to find a Model 28-1 you just hit the lottery. We thought they didn't exist until a forum member found one a few years ago & was kind enough to show us & let a few of us shoot it.
