I have an opportunity to purchase a 5 drawer 8x10 Brumberger paper safe on Craigslist. Though the rolltop will fully articulate, the seller confirms that it hangs up in the full open position and once again half-way down. Otherwise from the photos, it appears to be in good shape.

Before I drive 35 miles to check it out myself, does anyone know what my chances are of tinkering with it to get it to work correctly?
