Outer Limits 4x4 Board

Looking at buying a second hand warn high mount soon.
Is the only model the 8274 ? or were there other models made along the
way ? Just want to make sure the model I buy can be upgraded with motors etc.

Cheers

8274 is the one you want there were some before this and the 8274-50 which is the same just the 50 year anniversary.

8274 it is then

Some of the early ones had akey shaft for the motor run than a spline. It is a very simple and cheap upgrade so don't worry about that.

all high mounds in theory, are the same basic design, nothing much (except for the aforementioned) motor shaft, and the top hat free spool activation, solenoid arrangement and uhh colour scheme are all the changes you should encounter from a 1970s version vs a 2009 version
