How To Date Your Heller & Brightly Instruments:
We Offer Heller & Brightly Instrument Research
If you are researching your H&B instrument we may be able to
help. We have copies of a lot of the original Heller & Brightly records for instruments
with serial numbers over 6000. Please email us the serial number of your
instrument and we will see if we have the original records.
If we do have the records we will ask you to make a $10.00 donation and once we
receive the donation we will email you when the instrument was made, who
purchased it originally and the makers name.
***Please do not make a donation until you hear from us
that we actually have the records for your instrument.
We use PayPal for our donations but you do not need a PayPal account to
make a donation. PayPal works just like a credit card Processing Service
and if you have a credit card you can make a donation without having a PayPal
account.

If serial number is between 4400 and 6213 use Table I . These are
estimated numbers and are not expected to be in error by more that two or three
years.
If serial number is in range 6313 to 8287 consult table II these are
dates the serial numbers were authorized and in some cases the instruments were
not finished for several years.
If serial number is in range 6292 to 6670 consult table III. These were
instruments that were made in the years 1891 to 1897 and duplicated earlier
numbers in an effort to hide production from Charles Brightly. If the number is
listed in the table and the instrument is transit or level as indicated in
second column then the third column gives the year the number was authorized
otherwise the year is given in table II
If the number is 10,000 or above consult table IV.
For many of the instruments with serial numbers above 6000 the factory
records gives the name of the maker, an approximate date of sale and the name of
the purchaser.
