Larger guns were tested at a shooting range in Bordesley along a railway viaduct; however, the expansion of the city centre resulted in the closure of the shooting range. Proof may be rendered invalid if the firearm is damaged or modified significantly; at this point it is described as "out of proof" and must be re-proved before it can be sold or transferred. Note that the correct term for a satisfactorily tested firearm is ''Proved'', or ''Proven''. There are penalties for non-compliance with proof laws; a fine of £5,000 may be levied for selling an unproofed or out-of proof firearm, more if a number of firearms are involved in a transaction. Tampering with, or forging, a proof mark is regarded as even more serious. The Proof House still exists today, largely unchanged in both purpose and construction, although it offers a wider range of services including
