Summary

Here's a collection of old fire extinguishers and buckets all drawn full size so please scale to your needs.
The fire extinguishers are of the once common conical types and a cylindrical version that lasted longer.
The fire bucket was a once common sight in public spaces such as railway stations. I have drawn two variants of bucket with the round bottomed version hung on a wall mounted rack or stand and a flat bottomed version that could be set on the ground. They were filled with either water or sand. If filled with sand they usually had a load of stubbed out cigarettes in them too!
They print ok down to 1/76 in ABS like resin.

Enjoy
