Yes, look at the dates in the pictures, I didn't buy it but do have regular search using "picclick" to get around geo-blocking, that how I knew about this one, seeing 8TEN1944 confirmed it. I already own the Solartron device in question, which was bought locally.
Using the eBay provided international shipping, the buyer agrees to the T&Cs, which allow the third party shipping provider to prevent shipping outside the country, for whatever reason they decide, they never reveal why and can't be reasoned with.
They are then allowed to do with it what they like, this can be sending to a liquidator for resale, or disposing of it. The buyer & seller are never left out of pocket and the third party reseller allows them to recover some or all of the funds.
Looking through the first page of 8TEN1944, reveals many other types of items that are a problem for GSP/EIS, there are;
Items that may contain batteries, eg vintage calculator, pocket radio, watches,
Items that may contain gas/fuel or liquids, eg chainsaw, perfume,
Vehicle parts, eg bike frame, car parts,
Items with wood, eg saxaphone in case, speakers.
Items that are weapons, eg, sword, claw,
Medical equipment.
There are various things I can't explain, eg, Star wars toy, various Pokemon related things and clothing.
Using USPS, Fedex & DHL to send the items to me, I've not had problems sending vintage electronics (some with hazardous components) and chainsaws, except the one time the box was leaking gas out.

They always arrive, but sometimes get damaged, due to lack of packing material, or customs agents aggressively cutting open the box, recently had this with a HP analog voltmeter, front was slashed.
The new problems mentioned at the computer forum also mention problems importing into the US, I can't comment on this.
I'm very aware some sellers are hunting for old TE, both for metal recovery and attempting to resell parts, this applies to feeBay, radio rally sales and traditional auctions.
