Notes:

The #(21)234 GP7 was produced from 1959 through 1961, and it includes two variations. The first variation produced in 1959 and 1960, as shown in the photo, has long steps. The second variation produced in 1961 has short steps. The reason for the short steps is that when Gilbert went to the new Pike-Master systems, the radius of the track was such that the steps had to be shortened to allow to the GP7 to negotiate the curves of the new Pike-Master track. Both variations have a bell located inside the chassis with a clapper that is attached to the axle so the bell rings as the locomotive moves.

This shows both the pre-production model in the foreground and the production model with the yellow chassis in the back. Because of this feature, this locomotive has the nickname the 'Bell Ringer'.

This photo is not of the complete 370, but it shows a Gilbert prototype using that model's chassis, without the typical weight and the conventional old style reversing unit. This was done to make room for the brass bell assembly. In place of the typical reversing unit the factory designers/inventors installed a slide switch for manual reversing of the loco. Eventually this bell ringer mechanism was available in the 1959 (21)234 C&O Bell Ringer Locomotive that was part of the 1959 Defender Set.

Notes:

GP in T & P orange & black livery, dual units with one being powered (single motor) and horn, other being the dummy, one numbered 374, the other 375. The factory seemed confused and put the powered chassis in either numbered shell.

The photo shows two #375 models. The pair usually came as #374 and #375 where one was powered and the other not, but the shells could easily be reversed. This photo also shows the different styles of lettering fonts used. The dummy #375 sits on a #377 chassis (watch out for that when you buy these models).

Notes:

This is the first KC-produced GP engine, and it's rather rare. It came with a horn. Reproductions of it are rampant; the date stamp in the shell is about the only way to authenticate one.
