Thats a genuine Mid run Model 2 Tin wheel Rotomo.

HG Palmer did not make or name any mowers Rotomo"

The HG Palmer 2S base is higher and has different axle mounts,engine,handle bars and various other parts. And was also made 3 or more years later.

Simply, this a genuine Model 2 Rotomo,....With a Hg Palmer badge fitted.

Remove the badge, ebay it 30-50$ and buy the Correct Sad face Victa 18 badge if you like.

A few incorrect parts and rough repairs will lower this machines value, but overall its a fairly tidy Roto.
