As previously stated, I have visited the premises which is a residential property with a workshop in the rear garden. It looks like a husband & wife small business, so the claim that someone's on holiday is probably genuine. On previous experience of dealing with them, I'm sure that they would resolve the situation, given the opportunity.
As an aside, if you look at current scrap metal prices, I'm surprised they aren't charging to store the old prop, seeing as the 4rse has dropped out of the market.
