Two versions of the 0 gauge 215 crossing gate, the bottom one never had finials.

Circa 1923-1930 - This is the 0 gauge No. 215; Note the different gates from the No. 216s below. 

Circa 1923-1927 - Wide gauge version with wider gate and crossing sign. The example below has "DANGER" sign while the example above just reads "RAILWAY CROSSING". The example below that has a plain crossing sign and maybe something that was added on later by a collector. There are also reported to be some examples with a whistle sign.
