Hey,
Havnt been here for a while:)
Your mower like this one?Is it the Tiger or the Victa or the Villiers engine?
As for the rarity I think personaly they are rarer than the period Victa utilities but not the Sheerline series. As for value depends what you compare it to,its an early 60s run,so if you compare it to a sheerline id say definately NOT,if you put it up against a utility maybee yes,also I find that the Hg palmer 2 stroke with correct TIGER engine is more valuable than its other variants.
Either way its a different alternative to the victa series and is a nice addition to any collection,I like its archaic design and simplicity.
So to summarise if its a Hg palmer with correct Tiger engine and is complete with badge,rear flap and height adjust,then id say it would be a great resto project.:) as for value? I paid 50.00 for one and have seen one sell for over 250.00,they usually go for between 70.00 and 150.00,hope this helps:)
