Hi sodasopp,
Big warm welcome for this wonderful medium called the ODK.
The mower you have has had some changes made by a previous tenant at some stage as it no longer has its original engine. It would've been fitted with a Kirby Lauson 2.5Hp engine opposed to the Briggs as displayed.
I see you've gotten serious and already purchased a newly made catcher, so I guess you intend to do a complete back to bare metal restoration ? If so then lots of photos posted along the way will certainly help other members along with yourself to document the process.
Cheers,
BB.
