that wheel is an italvolante, but it is missing the center pad. hard to get as a separate piece.
my favorite is the Petri, either the 38cm or the 40cm. the downside is they have become expensive and the metal condition can vary, in addition there are leather covered petri wheels (CSL and hard to find) but most of them are a cast rubber with leather texture. the nardi has several variants and 2 appropriate sizes 39 cm and 36 cm (the 36 is almost too small) - wood w/ polished metal, wood with black metal, black leather with black metal, black leather with satin metal. with the RHD wood grab rail, i like the black steering wheel. in addition the nardi wood color and the RHD wood dash can be off color-wise.
