that's what it is. '68-'73 had the black fixed steel tube  supports..
'74-'79 they were adjustable retracting square  galvanized stock.  what you have
is the '68-'73 westy front childs  cot.

Hi  all;
I was just rummaging thru the basement and may have found the long  lost
front childs cot from my ol' 68 campmobile.  I'm just not  sure.  It's appox.
56" long (black steel rod supports).  Can anybody  give me correct
dimensions and maybe a pic of the ends that connect to the  pillars.  Any identifying
marks would be helpful.
It's in surprisingly  good shape.  Samba search has yielded no real
results.

Thanks
Dave  B.
