Lionel 242 Scout Locomotive Smoke Unit?

The 200 series Scout locomotives almost all had the same shell and motor, so any mechanical parts for one should fit in the others. Exception would be the 233 I believe.

I put a 236-50 smoke unit in a 246 Scout, easy install, works great. The 200 series of Scout locos are mechanically identical.

This was the donor loco.

Lionel Scout loco data from 1961 Lionel Service Manual

Loco  year   motor     motor magnets    smoke     grades

246   1959  246-200   1 low power            no           no     earlier versions had 246-100 motor
245   1959  245-200   2 low power            no           yes    earlier versions had 245-100 motor
236   1961  236-100   1 high power       236-50       yes    comes with 233W whistle tender
233   1961  233-100   2 high power       233-50       yes
235   1961  236-100   1 high power         no            yes

I think the 233 had a modified smoke unit for a different voltage range because it was made to run on an over-and-under set?

Thanks for your responses!
