As stated earlier, that is an Apeco "Small World" trailer. I was on the verge of buying one, but the dealer sold
it out from under me.
They were made for a very short time. The name Apeco is an acronym for American Photographic Equipment Company! They started out in business making equipment for photographers.
I'm extremely interested in finding and purchasing one of these odd little trailers. If you or anyone else has one for sale
, please contact me. Thanks!
