Offy 270 plans, still available?

[DiegoVV]

Hi fellow colleagues,

After the fantastic build (as always) of Mayhugh1, I´ve been lately actively looking to buy a copy of the Ron´s Colonna Offy plans, but it seems they´re not available anywhere on the internet.

I know this topic has been discussed a number of times in the past on this forum, but I´m still not able to find any solution.

Can anyone enlighten me? May be someone can sell me a copy?

Thank you very much.

According to this advertisement, there was an addendum to the plans, to improve the engine.

I read top down these two posts, but still no clue on where to buy today a copy. Ron Colonna stopped selling copies some time ago.
