Nice work Andy. Remember that only the receivers of the guns can be seen, so only the seams there need to be scraped off.
I might have three spare Browning .50s if you need them, I'll have a look in the spares box. I also think I've located the decal sheet with the 'No Step' markings - just got to check they're on the sheet, and the right size.
I'll let you know about both by tomorrow (Tuesday) at the latest.
