Order up the Toplicht Catalog. I don't know how Brazilian mail does, but I ordered a copy and had it in my grubby little hand within 4 days.
The Toplicht catalog is still auf Deutsche, but it has an English index. Or possibly...one of our German friends here would consent to translate where needed?
You might also check with Davey & Company (UK, http://www.davey.co.uk/). Their catalog is in English (but they are, unfortunately, wholesale-only. You might need to communicate with Davey to determine an appropriate or local distributor.) I've got a Davey catalog at work...I'll check it in the AM and see whether they list an appropriate winch handle for you.
