Choosing a Flagstop station for a diecast model railroad can be straightforward when the scale and construction match your layout-but it becomes less clear when two nearly identical HO kits carry different listed prices. Here, both choices are Alexander Scale Models Pennsylvania Flagstop kits with the same stated 1:87 scale, HO gauge, balsawood-and-diecast materials, and unassembled-kit format. The key decision is whether the higher-priced title wording adds anything meaningful for your project.
Quick verdict
Choose Alexander Scale Models Kit 1/87 HO RS-631 Flagstop Pennsylvania if your priority is the lower listed price for the same stated HO-scale Flagstop scene and unassembled build. Choose Alexander Scale Models Kit 1/87 HO RS-631 Flagstop Pennsylvania Unassembled only when matching that exact titled version is important to you. The listed-price spread is $7.99, while the core stated specifications align.

Where each kit wins
The Alexander Scale Models Kit 1/87 HO RS-631 Flagstop Pennsylvania wins on listed price. Its USD 27.00 price is the more direct choice for adding a Pennsylvania Flagstop building while retaining the same stated scale, gauge, materials, and assembly format as the other kit.

"Unassembled" appears directly in its title, which may matter if that is the precise wording you are using to organize or match a project search. It does not represent a different assembly state: both are identified as unassembled kits.
Product notes
Alexander Scale Models Kit 1/87 HO RS-631 Flagstop Pennsylvania
This is the clearer pick for a shopper focused on the listed USD 27.00 price. It is a new, vintage Alexander Scale Models railroad-themed Flagstop kit made in the United States, with HO gauge and 1:87 scale stated for the building. Balsawood and diecast are both named as materials, giving the kit a specific material combination for a Pennsylvania station scene. Its most concrete advantage in this head-to-head is simple: it carries the lower listed price while sharing the other kit's stated scale, gauge, material, type, and unassembled construction. The tradeoff is that it remains an unassembled kit, so it is intended for a hobbyist who wants to assemble the station rather than place a completed building immediately.
Alexander Scale Models Kit 1/87 HO RS-631 Flagstop Pennsylvania Unassembled
Pick this version when the exact "Flagstop Pennsylvania Unassembled" title wording is the detail you want to match. The kit is also new, vintage, made in the United States, and built around the same HO-gauge, 1:87-scale railroad Flagstop concept. Like its counterpart, it specifies balsawood and diecast materials and is designated an Unassembled Kit, so it suits a builder looking to create the structure as part of an HO railroad scene. The limitation is its USD 34.99 listed price, which is $7.99 higher than the other Alexander Scale Models Flagstop Pennsylvania kit. Since the stated build format and core specifications are shared, that higher price is the main practical consideration.
Final choice by use case
For an HO layout builder seeking the lower listed price, choose Alexander Scale Models Kit 1/87 HO RS-631 Flagstop Pennsylvania. For a shopper who specifically wants the title that includes "Unassembled," choose Alexander Scale Models Kit 1/87 HO RS-631 Flagstop Pennsylvania Unassembled. In either case, you are choosing a 1:87 HO, balsawood-and-diecast, unassembled Pennsylvania Flagstop kit.
