Here's an unusual porcelain antenna strain stamped "IRUPE/INDUSTRIA ARGENTINA" "5H". Measures 12 3/4" long by 1 5/8" wide. Irupe is known (to me but unlisted last I checked on NIA website) to have made pintype insulators including spools. New discovery and Mint condition!

First email gets this cool porcelain antenna strain from Argentina for only $85 plus shipping. Thanks!
